Collective bands and yrast band alignments in 78Kr

Nuclear Physics A, 1996
The structure of the collective bands in 78Kr is studied within the framework of our deformed configuration mixing shell model based on Hartree-Fock states. The configuration space consists of the spherical single particle orbits 1p32, 0f52, 1p12 and 0g92 with 56Ni as the core.

Band bowing and band alignment in InGaN alloys

Applied Physics Letters, 2010
We use density functional theory calculations with the HSE06 hybrid exchange-correlation functional to investigate InGaN alloys and accurately determine band gaps and band alignments. We find a strong band-gap bowing at low In content. Band positions on an absolute energy scale are determined from surface calculations.

Fully-depleted dual P–N heterojunction with type-II band alignment and matched build-in electric field for high-efficient photocatalytic hydrogen production

International journal of hydrogen energy, 2021
In this work, a dual p-n heterojunction of Cu2O/Ni(OH)2/TiO2 with type-II band alignment and matched build-in electric field was fabricated. This dual p-n heterojunction promoted the separation and transfer of charge carriers, which is much more ...

ZnO-polyethylene interface: Band alignment

2017 International Symposium on Electrical Insulating Materials (ISEIM), 2017
Zinc oxide-polyethylene nanocomposites have a potential to be used for high voltage insulation. Here, we investigate electronic properties of zinc oxide-polyethylene interface using density functional theory. Interface states up to 1 eV below conduction band edge are found in polyethylene.
