1. A method for producing a ZnTe system compound semiconductor single crystal, comprising:
co-doping a first dopant and a second dopant into the ZnTe system compound semiconductor single crystal, the first dopant being for controlling a conductivity type of the ZnTe system compound semiconductor to n-type and comprising a Group 13 (3B) element, and the second dopant comprising a Group 2 (2A) element having a bond energy with a Te element equivalent to or larger than a bond energy between a Zn element and the Te element, when performing epitaxial growth of the ZnTe system compound semiconductor single crystal on a substrate.
