Device characterization of gallium nitride high electron mobility transistor with a boron nitride heat-spreading element

open access: yesВесці Нацыянальнай акадэміі навук Беларусі: Серыя фізіка-тэхнічных навук, 2023
A local thermal management solution for high electron mobility transistors based on GaN was developed using a BN layer as a heat-spreading element. The thermally conducting and electrically insulating nature of BN allows it to be placed close to the ...

Numerical investigation of PBDB-T:INTIC based bulk heterojunction organic solar cell with graphene derivatives as HTL

open access: yesResults in Surfaces and Interfaces
Graphene derivatives, with their exceptional mobility and tunable optical bandgap, have emerged as promising candidates as interfacial layers, particularly as hole transport layers (HTLs) in bulk heterojunction organic solar cells (BHJOSCs).

Global Rather Than Vertical‐Selective Saccadic Abnormalities in Progressive Supranuclear Palsy

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To test whether vertical saccades are preferentially affected in Progressive Supranuclear Palsy (PSP). Methods PSP patients (n = 24) were compared to age‐matched controls (n = 94) and two degenerative groups (Alzheimer's disease, n = 20; Lewy body disease, n = 50).
