β-Ga2O3 epitaxial growth on Fe-GaN template by non-vacuum mist CVD and its application in Schottky barrier diodes

AIP Advances, 2021
In this work, we report on demonstrating lateral β-Ga2O3 Schottky barrier diodes (SBDs) fabricated on Fe-GaN/sapphire (0001) substrates by using the non-vacuum, low-cost mist chemical vapor deposition (mist CVD) method for the first time.

Band gap of reduced graphene oxide tuned by controlling functional groups

, 2020
Reduced graphene oxide (rGO) is a material with a unique set of electrical and physical properties. The potential of rGO for numerous semiconductor applications, however, has not been fully realized because the dependence of its band gap on the chemical ...

Ultrathin wide band gap kesterites

Faraday Discussions, 2022
Thickness reduction of kesterite CZTS solar cells down to 250 nm is performed showing relatively small performance loss. The introduction of oxide passivation layers improves performance and a NaF treatment is used to make such back contact conductive.

Layer-Controlled Band Gap and Anisotropic Excitons in Phosphorene [PDF]

, 2014
The authors report that the band structure of few-layer black phosphorous is anisotropic and the band gap increases with the decrease in number of staking layers. The optical absorption and excitonic effects are also anisotropic.
