The semiconductor-electrolyte junction: Physical parameters determination by photocurrent measurement throughout the Cd1−xZnxTe alloy series

Abstract
p‐type Cd1−xZnxTe alloys with 0<x≤1 are studied by photoelectrochemical technique. An electron diffusion length in the range 2–4 μm is measured which changes with x. This information together with the large and constant value of the Urbach’s slope of the absorption tail (∼125 eV1) leads to the conclusion that the disorder in the alloys is slight in the whole composition range.
