Abstract
A structure for doping of III-V compounds is provided. The structure is a multi-layered structure in which layers of dopant are alternated with layers of initially undoped III-V compound. Dopant diffuses from the layers of dopant into the layers of III-V compound. The structure does not facilitate the introduction of impurities into the III-V compound during the diffusion of the dopant.
