Twisted MoS2 Bilayers as Functional Elements in Memtransistors: Hysteresis, Optical Signatures, and Photocurrent Kinetics

open access: yesAdvanced Electronic Materials, EarlyView.
ABSTRACT Layered 2D materials are considered as promising for memristive applications due to their ultimate vertical scalability compared to conventional semiconductor films and pronounced hysteresis properties. Bias‐resolved Raman and Photoluminescence mapping is used to quantify strain from phonon shifts and carrier density from the exciton‐trion ...

Low Thermal Resistance Architectures for AlGaN‐Based Semiconductor Devices

open access: yesAdvanced Electronic Materials, EarlyView.
Engineering channel thickness and substrate material significantly improves thermal management in AlGaN RF devices. A 5 nm AlGaN channel integrated on an AlN substrate achieved a record‐low thermal resistance of 3.96 K·mm${\rm K}\cdot{\rm mm}$/W, representing an 88.7% reduction compared with 500 nm AlGaN‐on‐sapphire devices.

A Quantitative Lithium Inventory Framework for Anode‐Free Lithium Metal Batteries

open access: yesAdvanced Energy Materials, EarlyView.
A component‐resolved lithium inventory framework quantitatively tracks Li redistribution across the cell in anode‐free NMC622||Cu pouch cells throughout cycling. Three sequential degradation stages are identified: formation‐driven cathode Li depletion, midlife inactive Li0 accumulation, and late‐stage runaway SEI thickening. The cathode, as the sole Li
