With the development of portable applications and electric vehicles, battery life becomes very important. In this application scenario, Static random access memory (SRAM) design should consider power consumption first. Because the power consumption is quadratic with the supply voltage, the main way to reduce the power consumption is to reduce the supply voltage. But it can significantly reduce the read stability and writing ability of the classical 6T cell. Moreover, as the development of CMOS process nodes, Static Noise Margin (SNM) will be further reduced. Therefore, this paper analyzes the 6T cell and proposes a highly stable 15T cell based on SMIC 28nm CMOS technology. The simulation results show that compared with 6T cell, 15T cell eliminates the half-select disturb, 6x improvement in read SNM at 0.6V supply, read delay reduced by 405ps, and increases 1x area overhead. © 2021 IEEE.

Tellurium-selenium (TexSe1-x) alloy compound is considered as an excellent light absorber layer for thin-film photodetector applications, owing to its suitable bandgap and excellent optoelectronic performance. Recently, the research on TexSe1-x photodetectors has achieved considerable progress, especially under electron and/or hole transport layer engineering to improve the device responsivity. However, the intrinsic growth mechanism of TexSe1-x thin film still needs investigation. In this work, based on the analysis of crystal growth thermodynamics and kinetics, Te0.7Se0.3 light absorber with optimal (100) growth orientation can be achieved through thermal evaporation of pre-alloyed Te0.7Se0.3 powder and atmosphere-assisted slow thermal annealing of Te0.7Se0.3 thin film. Thanks to the optimized Te0.7Se0.3 light absorber and Te0.7Se0.3/ZnO heterojunction interface, the champion self-powered thin-film photodetector possesses a wide spectral response range of 300–1600 nm, minimized dark current density of 3.1 × 10−5 mA cm−2, accompanied with satisfactory responsivity of 0.06 A W−1 and detectivity of 5.9 × 109 Jones at 1300 nm, and linear dynamic range exceeding 101 dB. Interestingly, an imaging system based on this photodetector can achieve high-precision color imaging and multispectral imaging from visible light to short wave infrared light, highlighting the intriguing application potential of Te0.7Se0.3 photodetectors. © 2025 Wiley-VCH GmbH.

A novel $\beta-\text{Ga}_{2}\mathrm{O}_{3}$ metal-oxide-semiconductor field-effect transistor (MOSFET) featured heterojunction field plate (HFP) is proposed to enhance its breakdown voltage $(BV)$ and reduce specific ON-resistance $(R_{\text{ON,SP}})$ , and its mechanism is investigated by simulation. The HFP is composed of P-NiO above the drift and regrown $\text{Ga}_{2}\mathrm{O}_{3}$ at drain side. The P-NiO and N-drift $\text{Ga}_{2}\mathrm{O}_{3}$ work like the P/N pillars of superjunction. Thus, the HFP structure not only modulates the surface electric field (E-field) distribution to improve the $BV$ in the off-state, but also introduces assisted depletion effect to improve the drift doping concentration to reduce the $R_{\text{ON,SP}}$ . Based on the charge balance principle between the P-NiO and N-drift $\text{Ga}_{2}\mathrm{O}_{3}$ , the $BV$ , power-figure-of-merit $\left(\text{PFOM}=B V^2 / \text{Ron}, \text{SP}\right)$ and $R_{\text{ON},\text{SP}}$ of the proposed HFP $\beta-\text{Ga}_{2}\mathrm{O}_{3}$ MOSFET are improved by 40.5%, 230.8% and 40.3% compared with those of conventional $\beta-\text{Ga}_{2}\mathrm{O}_{3}$ MOSFET at the same dimensions. Thus, this proposed device provides a new design strategy for high-power $\beta-\text{Ga}_{2}\mathrm{O}_{3}$ MOSFETs.

A novel SOI lateral insulated gate bipolar transistor (LIGBT) featuring double-integrated NMOS (DNM) is proposed and investigated. The DNM (MOS1 and MOS2) self-adaptively controls the states of parasitic diode $\mathrm{D}_0$ (P-well/N+ cathode). In the on state, the Do adaptively turns on to enhance the conductivity modulation effect to improve the on-state voltage drop $(V_{\mathrm{o}\mathrm{n}})$ . In the saturation and short circuit state with high anode voltage $(V_\text{AK})$ , the $\mathrm{D}_0$ is adaptively turned off and reverse-biased to reduce the saturation current $(I_{\mathrm{s}\mathrm{a}\mathrm{t}})$ and improve the latch-up immunity and achieve a better short-circuit withstanding time $(t_{\mathrm{s}\mathrm{c}})$ . During turning-off period with increasing $V_{\text{AK}}$ , the DNM LIGBT significantly reduces turnoff loss $(E_{\text{off}})$ due to the adaptively turn-on MOS1 providing a low resistance path to extract the stored carriers quickly. DNM LIGBT decreases the $E_{\text{off}}$ by 76% at the same $V_{\text{on}}$ compared with the SCM LIGBT and improves $t_{\mathrm{s}\mathrm{c}}$ by 252% and 27% compared with those of Con. and SCM LIGBTs.

The SiC substrate cost accounts for >50% of final device cost, and its manufacturing suffers from a high carbon footprint. To address this challenge, this work demonstrates a novel 150 mm single-crystal SiC engineered substrate, which homogeneously integrates a prime-grade SiC layer onto a dummy-grade SiC substrate by surface-active bonding. This engineered substrate reuses low-grade SiC substrates, which are often disposed as wastes in the MOSFET industrial production, as well as recycling the high-grade wafer for over 30 times. It thus can enable a drastic reduction in the substrate cost (by ~40%) and the associated carbon footprint. The engineered substrate demonstrates a defect density as low as prime-grade substrate, a low thermal boundary resistance (TBR) of 2.8 m2K/GW, as well as very small electric field at the bonded interface. The TBR is among the lowest reported for the SiC interfaces bonded with SiC, GaN, and Ga2O3. The 150 mm, 1200 V-class SiC epi grown on this substrate achieved a high killer-defect-free yield of 99.2%. The 1200 V, 20 mΩ SiC MOSFETs fabricated on this 150 mm epi demonstrate a yield over 70% (for IDSS250 A, 10 ms surge current. To the best of our knowledge, this is the first report of the wafer-level device data and high-current robustness for a SiC engineering substrate. These results show the great potential of this new substrate technology to enable more economical and sustainable SiC power electronics. © 2024 IEEE.

A band-to-band tunneling FET (TFET) with an atomical two-dimensional (2D) channel is a potential candidate for the next-generation electronic device in view of its steep subthreshold swing and low power consumption. However, how to establish a precise physical model between the band property of 2D channel materials and the device performance of 2D TFETs is the key to accelerate their practical applications. Herein, through high-throughput first-principles calculations, we study the tunneling transport properties of 44 representative 2D materials with four kinds of crystal system. Particularly, we propose a well-defined and striking exponential scaling law (SS=AeBmr+C) between the subthreshold swings (SSs) and reduced effective masses (mr) of 10-nm TFETs. According to the exponential model, 2D orthorhombic and trigonal crystal TFETs with the steep SS hold the reduced effective masses of more than 0.1 and 0.2m0, which could inhibit tunneling leakage current. These insights provide guidance for material screening in the construction of post-Moore 2D low-power transistors.

Molybdenum disulfide (MoS_(2)) with low cost, high activity and high earth abundance has been found to be a promising catalyst for the hydrogen evolution reaction (HER), but its catalytic activity is considerably limited due to its inert basal planes. Here, through the combination of theory and experiment, we propose that doping Ni in MoS_(2) as catalyst can make it have excellent catalytic activity in different reaction systems. In the EY/TEOA system, the maximum hydrogen production rate of EY/Ni-Mo-S is 2.72 times higher than that of pure EY, which confirms the strong hydrogen evolution activity of Ni-Mo-S nanosheets as catalysts. In the lactic acid and Na_(2)S/Na_(2)SO_(3) systems, when Ni-Mo-S is used as co-catalyst to compound with ZnIn_(2)S_(4) (termed as Ni-Mo-S/ZnIn_(2)S_(4)), the maximum hydrogen evolution rates in the two systems are 5.28 and 2.33 times higher than those of pure ZnIn_(2)S_(4), respectively. The difference in HER enhancement is because different systems lead to different sources of protons, thus affecting hydrogen evolution activity. Theoretically, we further demonstrate that the Ni-Mo-S nanosheets have a narrower band gap than MoS_(2), which is conducive to the rapid transfer of charge carriers and thus result in multi-photocatalytic reaction systems with excellent activity. The proposed atomic doping strategy provides a simple and promising approach for the design of photocatalysts with high activity and stability in multi-reaction systems.
