Toward Reliable Metal Halide Perovskite FETs: From Electronic Structure and Device Physics to Stability and Performance Engineering

Advanced Electronic Materials, EarlyView.
Metal halide perovskite field‐effect transistors (PeFETs) offer great promise for flexible, low‐cost, and high‐performance due to their excellent charge carrier properties. However, challenges like ion migration, hysteresis, and instability limit their performance.

Optimal control set expansion method for three‐phase voltage source converter with slip window selection and online parameter modification

IET Power Electronics
Finite control set model predictive control (FCS‐MPC) has been widely used in the control of three‐phase voltage source converter (VSC), but its control performance declines sharply at low sampling frequencies.

Organic Electrochemical Transistors and Foreign Body Reaction: First Steps Toward Long‐Term Implantable Biosensing

Advanced Electronic Materials, EarlyView.
Organic Electrochemical Transistors (OECT) have been applied as implanted sensors in recent years. However, Foreign Body Reaction (FBR) effects on OECT performance are still underexplored. Here, we analyze OECT operation when covered by FBR‐related proteins in an in vitro scenario.

Reduced Variability in Threshold Switches Using Heterostructures of SiOx and Vertically Aligned MoS2

Advanced Electronic Materials, EarlyView.
Heterostructures of SiOx and vertically aligned MoS2 exhibit reliable threshold switching by guiding Ag ion migration through van der Waals gaps. Compared to SiOx‐only devices, these heterostructures demonstrate higher switching voltages, faster switching speeds, and reduced variability.
