Mechanisms for p-type behavior of ZnO, Zn${}_{1-x}$Mg${}_x$O and related oxide semiconductors

Daniel F. Urban, Wolfgang Körner, Christian Elsässer

Possibilities of turning intrinsically n-type oxide semiconductors like ZnO and Zn${}_{1-x}$Mg${}_x$O into p-type materials are investigated. Motivated by recent experiments on Zn$_{1-…
