Both the compounds mentioned are semiconductors. The atomic species required for making
InAs (Indium Arsenide) is Indium which is is 3rd group element and Arsenic which is group 5th
element. To make InSb(Indium Antimonide) the atomic species required is Indium which is 3rd
group element and Antimony which is again 5th group element. InSb is a semiconductor which
has narrow bandgap of 0.17ev at toom temperature. Owing to its low band gap it is generally
used in infrared sensors application.
