ABSTRACT
Minority carrier diffusion length and lifetime in p-Zn0.9Mg0.1O 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 Zn0.9Mg0.1O.
