摘要：

CuInTe2 is a ternary semiconductor that crystallize in the chalcopyrite structure of space group 142d. X-ray diffraction measurements up to 30 GPa were carried out on this material at the energy dispersive station DW11 of the LURE-Orsay, France. A phase transition was observed at 5.9 GPa and this high pressure phase have been indexed as cubic NaCl-type estructure. The bulk moduli are 62 GPa for the chalcopyrite phase and 85 GPa for the cubic phase. The volume reduction at the transition pressure is about 9.8 %
