Precise Tailoring of Charge Transport Characteristics in Zr and Hf Doped Indium Tin Oxide Thin Film Transistors

open access: yesAdvanced Electronic Materials, EarlyView.
Zirconium, hafnium, and mixed zirconium/hafnium doped indium tin oxide thin films are accessible by atomic layer deposition. The amorphous functional films are about 8 nm thick and show a high interdiffusion of all elements. Their transistor characteristics can be modulated depending on the amount of Zr and Hf oxide phases incorporated in these thin ...

Effect of Gate Length Relative to Recess Coverage on the Performance of Enhancement‐Mode β‐Ga2O3 MOSFETs

open access: yesAdvanced Electronic Materials, EarlyView.
Gate‐length engineering in recessed‐gate enhancement‐mode β‐Ga2O3 metal‐oxide‐semiconductor filed effect transistors was investigated by extending the gate to fully cover the etched recess. Complete recess coverage improves electrostatic control, reduces series resistance, shifts the threshold voltage positively, and enhances mobility, on‐resistance ...

Decoding Short‐Range Order in Amorphous Two‐Dimensional Nanosheets for Efficient and Durable Ampere‐Level Seawater Electrolysis: A Case Study of Amorphous Ni(OH)2

open access: yesAdvanced Energy Materials, EarlyView.
This work uncovers the atomic‐scale origins of exceptional HER performance in amorphous Ni(OH)2 nanosheets by combining atom probe tomography, DFT simulations, and operando spectroscopy. We identify distinct short‐range‐order motifs that accelerate water dissociation, proton transport, and hydrogen adsorption. Embedding Pt single atoms further enhances
