This work reports the impact of hetero gate oxide and dielectric pocket on the performance of conventional TFET. The conventional TFET has been optimized by introducing hetero gate oxide of HfO2-SiO2 and dielectric air-pocket. Both these approaches improve the lateral electric field at the source-channel interface and weakens the lateral electric field at the drain-channel interface. Hence, the ON-current is enhanced and OFF-current is reduced. At last, the optimized value of work-function of the gate metal has been obtained at 4.3 eV. The TCAD simulation results show a significant increase in ON-current (ION = 10.24 × 10−4) and reduction in leakage current (IOFF = 9.659 × 10−17). The value of ION/IOFF ratio and subthreshold swing was found to be 1.06 × 1013 and 11.776 mV/decade respectively that confirms a considerable improvement in the performance of the proposed TFET structure. The transconductance for the proposed device structure was found to be 1.935mS. These improvements confirm that the proposed device DP-HGO-DG-TFET is suitable for high frequency and low power applications. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

The progress in semiconductor technology has played a crucial role in enhancing human existence by introducing significant innovations. This has been achieved by moving away from traditional planar structures and the use of Silicon Dioxide (SiO2) as an oxide material. Instead, non-planar transistor structures like Fin Shaped Field Effect Transistor (FinFET) have been designed utilizing high-k (HK) dielectric constant oxide materials and metal gates (MG), leading to revolutionary advancements. Ashby’s approach to materials selection offers an organized and methodical technique for researchers to make informed choices based on performance objectives, material attributes, and environmental factors. The purpose of this article is to use Ashby’s technique in an effort to choose the prime oxide material from a range of HK materials. Gallium Arsenide (GaAs) is a versatile metal gate material with relative benefits for a range of applications. GaAs’s distinct properties, which include high electron mobility, a wide band gap, low resistivity, a high breakdown voltage, low noise performance, and compatibility with III–V compound semiconductors, make it an essential material for a wide range of applications in high-frequency electronics, optoelectronics, and power devices. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

In the last few decades, solar photovoltaic (PV)-based DC microgrids (MG) have become increasingly popular in applications such as electric vehicle (EV) charging and domestic and commercial power supplies. However, due to the uncertainty in solar power generation, the reliability of such systems is low for standalone applications, and hence, energy storage systems (ESS) are necessary to maintain power flow when power generation is not sufficient due to low irradiance or during night time. In solutions where batteries are used as ESS is bulky, heavy, and slow in response due to low power density, and therefore, not suitable for applications requiring a fast transient response. Fuel cell (FC) technology on the other hand has become a promising non-conventional energy source featuring both high energy density and power availability, though has slow dynamic response. Furthermore, the compactness and portable feature of FC enable it to beused in almost every field that uses battery as ESS (BESS). In this work, an existing DC MG consisting of solar PV, BESS, and DC load is considered. The solar PV and the battery are connected to the MG DC bus via buck and bidirectional DC–DC converters, respectively, whereas the FC is integrated using a boost converter. The Perturb and Observe (P&O) maximum power point tracking (MPPT) algorithm is implemented to track the maximum power point (MPP) of both PV and FC. Here, the DC bus voltage is maintained at 48 V by the bidirectional converter using a Proportional–Integral (PI) controller. This work highlights the MPPT of FC and the integration of solar PV, BESS, and FC to the DC MG leading to a cleaner and more efficient energy solution. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

Electric vehicles (EVs) are replacing conventional gasoline vehicles in the global transportation sector. The rise in penetration of EV load affects the reliability of the distribution systems (DSs). Reliability assessment is vital for designing DSs that operate economically and lessen customer load disruptions. It is important to achieve acceptable reliability regardless of the source, whether it is a distributed system, an electric utility system, or any other type. The integration of EVs and renewable resources (RRs) such as solar energy are significant feature of modern power system networks. The integration of solar energy acts as a backup option by supporting the power supply to the existing DS and improving the system’s reliability. Various reliability indices (RIs) can measure the duration and frequency of customer disruptions over an exact time. The main aim is to achieve consumer satisfaction, which needs proper planning. This paper confers a comprehensive study of different RIs and their importance in the power system. The reliability analysis is accomplished on an IEEE-33 bus radial DS after integrating EV load and solar energy source by applying teaching–learning-based optimization. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

The electromagnetic compatibility (EMC) testing standard requires that the electric drive system conduct EMC testing on a test bench under a simulated load. The shaft current generated by the test bench enters the interior of the anechoic chamber through a through-wall shaft, affecting the background noise of the anechoic chamber and the EMC testing results of the electric drive system. At the same time, the through-wall shaft passing through the shielding wall of the anechoic chamber can cause serious electromagnetic leakage. In this paper, the electromagnetic simulation model of the test bench and the semi-anechoic chamber is built, and the interference path of the shaft current and the shielding effectiveness of the system are studied. Through simulation, it is found that installing the shielding cover and grounding the test system can improve the shielding effectiveness of the test system. According to the standard, the actual load testing system is subjected to background noise testing, and the load testing system is optimized and designed based on electromagnetic simulation results. Ultimately, the background noise of the semi-anechoic chamber is lower than the GB/T 18,655-2018 5-level limit of 35 dBμV/m, verifying the effectiveness of the rectification and optimization. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

The intelligent transformation of traditional container terminals has become one of the main trends in the construction of smart ports. Among them, upgrading the traditional manned container trucks to unmanned ones and using the corresponding traffic control system to realize the unmanned horizontal transportation of the wharf is the key link of infrastructure transformation. As a new traffic phenomenon, the traffic conflict between manned trucks and unmanned trucks in ports has become a key bottleneck restricting the intelligent transformation and upgrading of ports. Based on the comprehensive analysis of the driving logic of the internal and external trucks in the smart port, this paper summarizes the conflict handling logic of the two in the typical traffic conflict scenarios in the port area. The simulation optimization evaluation modeling software AnyLogic is used to establish the port traffic conflict model based on the manned and unmanned trucks, and the impact of the two types of truck conflict behavior on the overall traffic of the port area is quantitatively analyzed according to the simulation results. The truck conflict model proposed in this paper can provide a reference for the transformation design of traditional container terminals to automated terminals, and provide decision support for the planning and layout of the port network under the background of improving smart ports. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

Photovoltaic (PV) modules are typically characterized by their I–V and P–V curves at fixed temperatures and varying irradiances. The module temperature, influenced by irradiance, is essential in simulating real-world conditions for PV modules. This study focuses on utilizing PVsyst software to evaluate the performance of polycrystalline PV modules in accordance with the specific requirements of Iraq such as dust and high temperature. Through an analysis of the module’s behavior under actual conditions, it was observed that the power output of the PV module experienced a 14.1% reduction compared to the control under Standard Test Conditions (STCs) due to the temperature rise caused by increased solar irradiation. Subsequently, when solar irradiance dropped to 200 W/m2, this reduction percentage escalated to 82.3%. Moreover, the rise in temperature adversely affected the module’s efficiency, although the influence of temperature exhibited a linear reduction on efficiency. This research provides valuable insights into the performance of polycrystalline PV modules and the impact of temperature variations on their power output and efficiency, contributing to the optimization of PV systems in Iraq. The results shown by this study contribute to helping to design solar energy systems in the future, considering the losses due to temperatures, for the purpose of providing additional energy output capacity to compensate for the losses. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.
