Published in 2018 at "Superlattices and Microstructures"

DOI: 10.1016/j.spmi.2018.04.011

Abstract: Abstract Characteristics of AlGaN-based deep-ultraviolet light-emitting diodes (DUV-LEDs) with step-like and Al-composition graded quantum wells have been investigated. The simulation results show that compared to DUV-LEDs with the conventional AlGaN multiple quantum wells (MQWs) structure,… read more here.

Published in 2017 at "ACS applied materials & interfaces"

DOI: 10.1021/acsami.7b09435

Abstract: Among transition metal dichalcogenide (TMD)-based composites, TMD/graphene-related material and bichalcogen TMD composites have been widely studied for application toward energy production via the hydrogen evolution reaction (HER). However, scarcely any literature explored the possibility of… read more here.
