Abstract

The independent particle model (IPM) coupled with the use of the virtual crystal approximation (VCA) which incorporates compositional disorder as an effective potential was used to compute the positron charge distribution in the cubic structured ternary alloy Zn1-xCdxSe. The positron charge density with respect to the variation of the mole fraction is discussed. The results show that positrons have a strong affinity for the anion than for the cation. This relative positron affinity should lead to the positron preferentially annihilating with the anion rather than the cation.
