Summary: This work investigates the voltage sweep behavior of quantum dot light-emitting diodes (QLEDs). It is found that red QLEDs with ZnMgO electron transport layer (ETL) experience a drop in efficiency under consecutive voltage sweeps, while devices with ZnO ETL show an increase in efficiency. The analysis reveals that the efficiency drop in ZnMgO devices is related to hole leakage mediated by trap states on ZnMgO nanoparticles. Furthermore, the hole leakage also causes rapid lifetime degradation of ZnMgO devices.

Summary: In the field of emerging heterogeneous power integration applications, power devices need to be fabricated on metal/glass/organics. Amorphous oxide semiconductors (AOSs) have become the dominant semiconductor material for low-temperature fabrication. The tradeoff between specific ON-resistance (R-ON,sp) and breakdown voltage (BV) in AOSs is discussed and found to be different from that in commonly used single-crystal semiconductors. An analytical model is developed to describe the unique dependence of carrier mobility on carrier concentration in AOSs, showing that R-ON,sp is proportional to BV4. Additionally, the use of a heavily doped drift region under a two-dimensional condition, such as reduced surface field (RESURF) condition, can resolve the issue of mobility degradation.

Summary: Changes in resting-state EEG microstate parameters were observed in patients with disorders of consciousness (DOCs) after high-definition transcranial direct current stimulation (HD-tDCS), indicating an improvement in consciousness. Specifically, the duration and coverage of class C microstates significantly increased in the responsive group (RE), while these changes have not been reported in the non-responsive group (N-RE). Our findings suggest that EEG neural signatures can be used to assess consciousness states, and that improvement in brain activity dynamics is associated with the recovery of DOCs.

Summary: This study aimed to investigate the modulatory effect of common variations in the oxytocin receptor gene (OXTR) on reward circuitry function and its relationship with empathy. Using functional connectivity and spontaneous local activity analyses in the nucleus accumbens (NAcc), the results showed that individuals with the rs2268493 TT genotype had lower functional connectivity between the NAcc and the medial prefrontal cortex (mPFC) as well as the inferior frontal gyrus (IFG). These findings suggest that common OXTR variations have a modulatory effect on the connection between the NAcc and the central hubs of empathic networks, providing insights into the neural basis of the modulatory effect of OXTR on empathic behavior.

Summary: By using Kelvin probe force microscopy and transient reflection spectroscopy techniques, we spatially resolved the variation in microscopic optoelectronic properties of perovskite hetero-junctions in metal-halide PSCs during operation and studied the light-soaking effect. The evolution of the junction was attributed to ion migration and self-poling induced by built-in voltage. The device performances were correlated with the changes in electrostatic potential distribution and interfacial carrier dynamics. Our results present a new route for studying the complex operation mechanism in PSCs.

Furthermore, a full cell using a pre-treated anode demonstrates high initial Coulombic efficiency and capacity retention after 100 cycles.
