Abstract
Minority carrier diffusion length and lifetime in p- Zn0.9 Mg0.1 O doped with phosphorus were obtained from local electron beam irradiation measurements. The irradiation resulted in an increase of up to 25% in minority electron diffusion length from the initial value of ~2.12 μm and in a simultaneous decrease of the peak near-bandedge cathodoluminescence intensity. The observed phenomena are attributed to charging of phosphorus-related deep acceptor level(s), which is consistent with the activation energy of 256±20 meV found for the effect of electron injection in Zn0.9 Mg0.1 O.
