Electric quadrupole interaction of111Cd in the system Sb1−xMx (M=Ag,Cd,In,Sn), Sb2Te3, Bi2Te3 and In2Te3

We have performed TDPAC-measurements to investigate the static quadrupole interaction of111Cd in the classic semimetal Sb. The coupling constant depends on the concentration of small amounts of metal admixtures. The only exception is the system Sb1−xAgx. The temperature dependence of the efg in the narrow gap semiconductors Sb2Te3 and Bi2Te3 is similar to that one in Te. In contrast to these results the efg in the III–VI-semiconductor In2Te3 is temperature independent.
