Defects of Silicon Carbide can bring about different natures, and these natures often need to be avoided. However, they have a positive effect in using. The representative utilization of the defects is a variety of point defects of silicon carbide.
What Are Point Defects of [...]

Highlights
•A recessed structure was used on the GaAs/Si solar cells to reduce the current path.
•The associated series resistance was reduced by a recessed structure.
•The carrier recombination loss was improved due to pyramid-like recessed structure.
In this study, epitaxial layers of GaAs-based solar cells were grown [...]
GaAs pn diodes with heavily carbon-doped p-type GaAs grown by MOMBE were fabricated. The I-V and C-V characteristics were not significantly affected by the hole concentration of the p-GaAs although a lattice mismatch at the junction generates misfit dislocations. A good I-V characteristic with [...]
