Abstract

We have grown single crystals of CdSn(As1−xPx)2 solid solutions over the entire range of x. On the basis of the temperature dependence of the Hall coefficient and the Hall mobility, we conclude that there is a mixed carrier scattering mechanism in all of these solid solutions, over the entire temperature range from 100 to 500 K, involving both impurity ions and thermal lattice phonons. IR absorption and photoconductivity spectra show that the band gap in the solid solutions varies linearly with composition. We conclude that crystals in the range 0.5<x<0.95 may be used to fabricate IR photodetectors and emission sources operating from 1.1 to 1.7 µm.
