Summary: In this paper, the shifting process of the threshold voltage (V-TH) of p-GaN gate HEMTs under BTI stress was carefully monitored to uncover the main cause of this effect. HEMTs without TDGB stress showed a high V-TH shift of 0.62 V, while those subjected to 424 s of TDGB stress exhibited a limited V-TH shift of 0.16 V. The mechanism behind this is the Schottky barrier lowering effect induced by TDGB stress, which enhances hole injection from the gate metal to the p-GaN layer, thereby improving V-TH stability by replenishing lost holes during BTI stress. This study provides experimental evidence that the gate Schottky barrier plays a dominant role in the BTI effect of p-GaN gate HEMTs.

Summary: The channel temperature distribution and breakdown points are difficult to monitor for traditional p-GaN gate HEMTs due to the opaque metal gate. In this study, p-GaN gate HEMTs with transparent indium tin oxide (ITO) were processed, enabling the use of ultraviolet reflectivity thermal imaging equipment to capture the desired information. The findings reveal that heat concentration occurs near the gate field in the access area under high power stress, and the sidewall of p-GaN is identified as the weakest spot.

Summary: A multifunctional Lewis acid, p-toluenesulfonic acid (TsOH), is used to optimize and tune the properties of single-wall carbon nanotube/silicon (SWCNT/Si) solar cells. TsOH acts as a charge transfer doping agent, optimizing the conductivity and work function of SWCNT films. Additionally, a chemical bridge is formed at the interface of SWCNT/Si heterojunction, effectively suppressing carrier recombination and enhancing the photocurrent. The TsOH coating also functions as an antireflection layer, leading to an increase in the power conversion efficiency.

Summary: Lead halide perovskite nanocrystals have potential as x-ray scintillators, but suffer from toxicity issues and low light yield. Bivalent europium ions (Eu2+) are a prospective replacement for lead due to efficient and self-absorption-free d-f transition. Solution-processed organic-inorganic hybrid halide BA(10)EuI(12) single crystals were demonstrated for the first time, exhibiting high photoluminescence quantum yield, large Stokes shift, and appreciable light yield. BA(10)EuI(12) also showed a short excited-state lifetime, linear scintillation response, low detection limit, and clear x-ray imaging capability.

Summary: Measuring specific contact resistivity (pc) is crucial for interface engineering in high efficiency solar cells. The Transfer Length Method (TLM) is commonly used for evaluating layer sheet resistance (Rsheet) and pc, but it is not suitable for metal/Transparent Conductive Oxide (TCO) interface evaluation in silicon heterojunction (SHJ) cells. This study investigates the parameters that restrict current confinement within the TCO, including mid-gap trap density (Dit) at the a-Si:H/c-Si interface and the activation energy (Ea = Ec - EF) variation of a-Si:H contact layers.

In this study, a three layers model is proposed to explain this effect, and the predictions of the model are validated through finite element method simulations and experiments. The results show that the model predictions are consistent with the indirect measurements, but not with the direct measurements. Additionally, it is inferred that the encapsulant plays a role after the solder failure.

Optical absorption mechanisms in qNL arrays were investigated using near-field scanning optical microscopy (NSOM), revealing that the enhancement is a result of the combination of effective antireflection coating, increased optical interactions between adjacent dielectrics for elevated light trapping, and strong light concentration due to the presence of qNLs.
