Problem: The Group 3A/Group 5A semiconductors are composed of equal amounts of atoms from Group 3A and Group 5A—for example, InP and GaAs. These types of semiconductors are used in light-emitting diodes and solid-state lasers. What would you add to make a p-type semiconductor from pure GaAs? How would you dope pure GaAs to make an n-type semiconductor?

FREE Expert Solution
  • n type semiconductors are created by doping a semiconductor with an electron donor atom. The term n-type comes from the negative charge of the electron. 
  • On the other hand, P type semiconductors are created by doping a semiconductor with an electron acceptor. The term p-type refers to the positive charge of a hole.
