Synthesis and thermal conductivities of ZnIn 2Te 4 and CdIn 2Te 4 with defect-chalcopyrite structure
ZnIn 2Te 4 and CdIn 2Te 4 have a defect-chalcopyrite tetragonal crystal structure with structural vacancies. In order to investigate the effects of vacancies on the lattice thermal conductivity (κ...
