The invention discloses a vapor phase epitaxy method for a gold-P doped HgCdTe material. The method is used for the vapor phase epitaxy of the gold-P doped HgCdTe material. At the temperature of 77 k, the gold-doped epitaxial material is 1.39E+0.2 cm<2>/Vs in the mobility, 2*10<18>cm<-3> in carrier concentration, and is a typical p type material; while under the same condition, non-gold-doped epitaxial material is 6.42E+0.4 cm<2>/Vs in mobility, 3*10<15>cm<-3> in carrier concentration is 3*10<15>cm<-3>, and is a typical n type material. Therefore, by adopting the method, the activation rate of gold doping is very high. The method has the advantages that the stability of the electrical parameter of doping type long-wave p material can be improved, and meanwhile, the doping can be achieved in vapor phase epitaxy equipment with low cost.
