Abstract: 
CdTe has historically been used in solar cells, infrared optical windows, and in radiation dectectors for x-rays, gamma-rays, beta particles and alpha particles. Doping of CdTe to make it n-type has been achieved, but is often limited by the well known phenomenon of “self-compensation”. The exact mechanisms for these effects are unknown, but are thought to be a synergistic effect between DX and AX defects. In this study we use first principles methods to pinpoint the doping limits of CdTe, and to understand the origins of these doping limits
