In this study, we make a comparable study of the hot-electron and hot-hole photodetectors with addressing the energy band bending, hot-carrier generation, transport, and emission processes based on ...

Electron scavenging by Cd ions is thermodynamically unviable since the metal redox potential does not match the position of the energy levels of the electron-hole pair on the photocatalyst, a fact ...

Excitons are electron-hole pairs in semiconductors that are electrostatically bound by strong Coulombic interactions. In ultrathin 2D semiconductors that are a few atoms thick (typically ~0.7 nm ...

From left to right: NUS researchers Assoc Prof. Lu Jiong, Dr. Qiu Zhizhan, and Mr. Han Yixuan were part of the multidisciplinary research team that visualized elusive electron-hole crystals with their ...

DGIST identifies what causes electron-hole separation in thin-film solar cells to increase solar cell efficiency Peer-Reviewed Publication DGIST (Daegu Gyeongbuk Institute of Science and Technology) ...

Electron Vs. Hole Movement: When an external voltage is applied to a semiconductor, it creates an electric field. This electric field pushes electrons in one direction (conventional current flow).

One of the most fascinating phases of matter is the supersolid phase. The supersolid phase of matter juxtaposes two a priori conflicting physical properties: a long range ordered structure phase and ...

Both sides now: artist's impression of bilayer graphene with an electron-hole symmetric double quantum dot, where the electron and the hole are in different layers. (Courtesy: Sebastian Staacks) ...

To understand the effect of the inserted EDL on the holes in the active region, we take the middle QW as an example. The hole potential heights ΔE v of these four structures are 152.98, 151.04, 149.42 ...
