Mapping Band Alignment across Complex Oxide Heterointerfaces

Physical Review Letters, 2012
In this study, direct observation of the evolution of electronic structures across complex oxide interfaces has been revealed in the LaAlO(3)/SrTiO(3) model system using cross-sectional scanning tunneling microscopy and spectroscopy. The conduction and valence band structures across the LaAlO(3)/SrTiO(3) interface are spatially resolved at the atomic ...

Band Alignment in WSe₂–Graphene Heterostructures

ACS Nano, 2015
Using different types of WSe2 and graphene-based heterostructures, we experimentally determine the offset between the graphene neutrality point and the WSe2 conduction and valence band edges, as well as the WSe2 dielectric constant along the c-axis. In a first heterostructure, consisting of WSe2-on-graphene, we use the WSe2 layer as the top dielectric ...

Band alignment of ScAlN/GaN heterojunction

Applied Physics Letters, 2020
The natural band alignments of ScxAl1−xN/GaN heterojunctions, with Sc-contents ranging from 0% to 25%, are investigated by first-principles density functional theory with the local density approximation. Type-I ScxAl1−xN/GaN heterojunctions with large conduction band offsets (CBOs) and valence band offsets (VBOs) are found. The band alignment of nearly

Energy Band Alignment and Defect Synergistic Regulation Enable Air‐Solution‐Processed Kesterite Solar Cells With the Lowest VOC Deficit

Advances in Materials
The major challenge in preparing high‐performance Cu2ZnSn(S,Se)4 solar cells is the large open circuit voltage deficit (VOC‐def). A new strategy utilizing the synergistic substitution of Ag and In dual cations has been proposed to simultaneously address ...

Band Alignment Engineering at Cu₂O/ZnO Heterointerfaces

ACS Applied Materials & Interfaces, 2016
Energy band alignments at heterointerfaces play a crucial role in defining the functionality of semiconductor devices, yet the search for material combinations with suitable band alignments remains a challenge for numerous applications. In this work, we demonstrate how changes in deposition conditions can dramatically influence the functional ...
