Photoluminescence decay measurements of n‐ and p‐type doped ZnSe grown by molecular beam epitaxy

Time‐resolved photoluminescence has been used to study carrier recombination in n‐ and p‐type doped ZnSe at room temperature. A band‐edge photoluminescence decay time of ∼240 ps has been measured for heavily doped n‐type material together with a relaxation time of a few microseconds for the associated deep‐level emission. The band‐edge photoluminescence decay time for p‐type doped material was ≤11 ps and is indicative of a high level of nonradiative Shockley–Read recombination.
