Band offsets, defects, and dipole layers in semiconductor heterojunctions [PDF]

, 1984
The role of defects in heterojunctions was investigated. The density of such defects required to pin the Fermi level or to affect the band offset was estimated using simple electrostatic considerations.

First-principles calculations of band offsets of Al xGa 1-xP-GaP(001) heterostructures

, 1997
A first-principles pseudopotential method combined with the virtual-crystal approximation (VCA) is used to calculate band offsets of Al xGa 1-xP-GaP(001) heterostructures.

Layer-dependent band offsets in metal/few-layer two-dimensional semiconductor junctions: Mechanisms and implications

Physical Review Research
For electronic devices based on two-dimensional semiconductors (2DSs), few-layer transition-metal dichalcogenides offer enhanced electrical performance over their monolayer counterparts.

Band offsets of n-type electron-selective contacts on cuprous oxide (Cu2O) for photovoltaics

, 2014
The development of cuprous oxide (Cu2O) photovoltaics (PVs) is limited by low device open-circuit voltages. A strong contributing factor to this underperformance is the conduction-band offset between Cu2O and its n-type heterojunction partner or electron-

A Prospective Study of Individuals at Risk of Multiple Sclerosis Informs the Design of Primary Prevention Studies

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective In multiple sclerosis, the optimal time for deploying a therapeutic intervention is before the central nervous system is damaged; given the success of trials treating the earliest stage of MS, the radiologically isolated syndrome, developing primary prevention strategies is an important next challenge.

Valence-band offsets of III-V alloy heterojunctions

, 1999
Valence band offsets at the heterointerface of lattice-matched ahoy semiconductors are investigated with theoretical calculation, which is based on average bond energy theory in conjunction with a cluster expansion method.

Valence band offsets for ALD SiO2 and Al2O3 on (InxGa1−x)2O3 for x = 0.25–0.74

APL Materials, 2019
The incorporation of In2O3 into Ga2O3 allows for tailoring of the bandgap over a wide range in (InxGa1−x)2O3, and this material is emerging as a candidate in transparent electrodes on optoelectronic devices, heterostructure transistors, photodetectors ...
