Zinc oxide thin films saturated with molybdenum were prepared by RF magnetron sputtering process. A surprising finding about the study is the electrical conductivity increases and then decreases with molybdenum sputtering power. Hall measurement study shows that the conductivity decrease is caused by decreased electron concentration. However, the electron mobility increases steadily with increased molybdenum sputtering power in the same range even though the molybdenum incorporation still increases. This is an indication that the electrical conduction no longer occurs through the molybdenum-doped ZnO grains. We conclude that the conduction changes from grains to grain boundaries as molybdenum sputtering power increases. It means molybdenum is precipitated at the grain boundaries and forms conducting channels besides zinc oxide grains. The high mobility conduction channel might be desired for devices using electron transport layers in their structures. © 2020 ECS - The Electrochemical Society.

Detection of single-electron charges in solid-state nanodevices is a key technique in semiconductor quantum bit readout for quantum information processing and probing electronic properties of nanostructures. This detection has been achieved using gate-based readouts and sensitive charge sensors including quantum dot charge sensors, with their detection speed enhanced by high-speed rf reflectometry. Recently, real-time processing of data from rf reflectometry has attracted much attention to quantum information processing. In this paper, we propose a sequential method based on Bayes’ theorem for estimating the charge state and compare its performance with the averaging approach and threshold judgment. When the noise variance differs between the empty and occupied states, the Bayesian approach demonstrates a lower error score, facilitating the extraction of more data points in real-time charge state estimation. In addition, the Bayesian approach outperforms the averaging method and threshold judgment in terms of error rates for charge state estimation, even during charge transitions. This technique is broadly applicable to single-electron detection and holds substantial utility for quantum bit readout and the operation of nanoprobes that utilize single-electron detection.

Anisometropia is due to the different refractive power of the left and right eyes, resulting in uneven eye focus and different diopters of the two eyes, resulting in asymmetric hyperopia, myopia and astigmatism. At present, it is not completely clear what causes anisometropia, but it may be caused by different refractive power of both eyes. The difference of binocular refractive power of normal vision people may be as high as 5%, but people with difference more than 5% are prone to binocular vision. The purpose of this study is to measure the changes of clear and blurred brain wave signals of vision. Through the relationship between brain wave signals and visual response, we analyze the attention and meditation curve of brain wave, and complete the fitting prescription lenses of anisometropia. © 2021 IEEE.

Excitons, bound electron-hole pairs, in Two-Dimensional Hybrid Organic Inorganic Perovskites (2D HOIPs) are capable of forming hybrid light-matter states known as exciton-polaritons (E-Ps) when the excitonic medium is confined in an optical cavity. In the case of 2D HOIPs, they can self-hybridize into E-Ps at specific thicknesses of the HOIP crystals that form a resonant optical cavity with the excitons. However, the fundamental properties of these self-hybridized E-Ps in 2D HOIPs, including their role in ultrafast energy and/or charge transfer at interfaces, remain unclear. Here, we demonstrate that > 0.5 µm thick 2D HOIP crystals on Au substrates are capable of supporting multiple-orders of self-hybridized E-P modes. These E-Ps have high Q factors (> 100) and modulate the optical dispersion for the crystal to enhance sub-gap absorption and emission. Through varying excitation energy and ultrafast measurements, we also confirm energy transfer from higher energy upper E-Ps to lower energy, lower E-Ps. Finally, we also demonstrate that E-Ps are capable of charge transport and transfer at interfaces. Our findings provide new insights into charge and energy transfer in E-Ps opening new opportunities towards their manipulation for polaritonic devices. © 2023, CC BY.

The process of wound healing is often obstructed by the prevalence of bacterial infection at the wound site. Hence, innovative strategies to alleviate infection is extremely necessary to realize effective wound recovery in a timely manner. Here, we report a self-activated composite dressing consisting of piezoelectric and photothermal functional layers for combating wound infection and provide the desired treatment. The synergistic dressing is functionalized with piezoelectric Poly-L-lactic acid (PLLA) which under the effect of ultrasound irradiation controllably generates reactive oxygen species (ROS) for antibacterial activity, thus facilitating the dressing to inhibit the growth of bacteria at the wound bed. Further, the dressing is modified with calcium peroxide (CaO2) which can effectively convert the generated ROS into molecular oxygen (O2) in presence of catalase enzyme for treating chronic hypoxia in the infected wounds. The sustained generation of O2 by the wound dressing augmented the cell proliferation, migration and tissue regeneration aiding in wound healing. By combining the inherent photothermal activity of reduced graphene oxide (rGO), the synergistic dressing under NIR irradiation enhanced the wound recovery by upregulating the heat shock protein 90 (Hsp90) secretion owing to the heat generation on the wounds. The results obtained demonstrate that the self-triggered multifunctional wound dressing is a promising candidate for clinical treatment of infected wounds with a user-friendly interface. © 2023 Elsevier B.V.

The unusual features of transient electronics to disintegrate the device after its use have gained popularity in the research community as well as in various fields which is not possible with conventional electronics. Different triggers such as wet, dry, and stimuli-based have been utilized for the degradation or dissolution of electronic devices. To date, wet based transience has been a dominant trigger because most of the bio-materials are soluble in aqueous and non-aqueous solutions. Due to this, the chemical dissolution, materials selection, devices functionalities, and configurations for the development of transient electronic devices are limited. To overcome this limitation, this report demonstrates the fabrication of electronic passive and active components with natural candelilla wax as a supporting substrate and further demonstrating the disintegration of the fabricated devices by light and heat. Further, the versatility of the fabrication process is demonstrated by patterning four different Transition Metal Dichalcogenides (TMDs) on wax substrate. The various patterned devices are exposed to heat and light triggers, and the lowest degradation time of ~ 30 seconds was achieved. The successful demonstration of wax based electronics opens up new avenues of research in transient based electronics for potential applications in security, sensors, antennas etc. © 2022, The Authors.

The field of next-generation microdisplays is flourishing. Relevant display technologies, such as mini-light emission diodes (mini-LEDs), micro-organic light emission diodes (micro-OLEDs), and micro-light emission diodes (micro-LEDs) are thus in the urgent stage of development. From this perspective, comprehensive and systematical analyzes are conducted for the aforesaid microdisplay configurations. A holistic view of microdisplay technologies is developed with the corresponding performance metrics, providing a path for miscellaneous scenarios. Among these scenarios, the applications in augmented reality (AR), virtual reality (VR), wearable devices, and head-up displays (HUD) are currently attracting considerable attention for deeper human-digital interactions. However, there is a multiplicity of obstacles and challenges hindering such development. Nevertheless, recent advances in microdisplay technologies hold tremendous promise for the paradigms of these applications, taking a leap forward for next-generation microdisplays. This review presents perspectives, relevant materials, and the technology landscape for such ongoing display technologies, offering guidance on the design of advanced microdisplays. © 2023 Wiley-VCH GmbH.
