which one among the following shows Direct BandGap?
-
Si
-
Ge
-
GaAsP
-
none of these.
C
Correct answer
Explanation
Direct bandgap semiconductors allow efficient light emission and absorption. GaAsP (Gallium Arsenide Phosphide) is a III-V direct bandgap material. Silicon and Germanium are indirect bandgap materials, making them poor for optoelectronic applications.
