It is direct band gap material.
GaP in an indirect band gap material
Yes it is. Most Sn (tin) materials as semiconductors are direct band gap materials. Silicon on the other hand is an indirect band gap material.
Yes it is.
Silicon is by all means an indirect band gap material.
Optical sources like LEDs use direct band gap so that conduction band electorn can recombine directly with a hole in valence band .
The Gap Band was created in 1967.
carbon is not used as the semiconductor because it has larger band gap than silicon and germenium

The Gap Band III was created in 1980.
The Gap Band II was created in 1979.
Gap Band IV was created in 1981.
