Visualizing band offsets and edge states in bilayer–monolayer transition metal dichalcogenides lateral heterojunction [PDF]
Nature Communications, 2016 Heterojunctions of two-dimensional materials are used to design electronic and optoelectronic devices. Here, the authors show that zigzag terraces between monolayers and bilayers form atomically sharp type-I heterojunctions, resulting in a wire-like ...

Composition dependent band offsets of ZnO and its ternary alloys. [PDF]
Sci Rep, 2017 We report the calculated fundamental band gaps of wurtzite ternary alloys Zn1−xMxO (M = Mg, Cd) and the band offsets of the ZnO/Zn1−xMxO heterojunctions, these II-VI materials are important for electronics and optoelectronics. Our calculation is based on

Computing with DFT Band Offsets at Semiconductor Interfaces: A Comparison of Two Methods [PDF]
Nanomaterials, 2021 Two DFT-based methods using hybrid functionals and plane-averaged profiles of the Hartree potential (individual slabs versus vacuum and alternating slabs of both materials), which are frequently used to predict or estimate the offset between bands at ...

Band-offsets scaling of low-index Ge/native-oxide heterostructures [PDF]
Scientific ReportsWe investigate, through XPS and AFM, the pseudo layer-by-layer growth of Ge native oxide across Ge(001), (110) and (111) surfaces in ambient environment. More significantly, our study reveals a universal set of valence and conduction band offset (VBO and

Band offsets in ITO/Ga2O3 heterostructures [PDF]
Applied Surface Science, 2017 Abstract The valence band offsets in rf-sputtered Indium Tin Oxide (ITO)/single crystal β-Ga2O3 (ITO/Ga2O3) heterostructures were measured with X-Ray Photoelectron Spectroscopy using the Kraut method. The bandgaps of the component materials in the heterostructure were determined by Reflection Electron Energy Loss Spectroscopy as 4.6 eV for Ga2O3 and ...
