Compound semiconductors

Which is classified as a III-V compound semiconductor?

  1. ASiC
  2. BGaN
  3. CZnSe
Show answer and explanation

Answer: B. GaN

GaN is a III-V compound semiconductor made of gallium (Ga), a group III element, and nitrogen (N), a group V element. SiC is a compound of two group IV elements (IV-IV), and ZnSe is a II-VI compound semiconductor made of zinc (group II) and selenium (group VI).
