Phase segregation in Mg${}_x$Zn${}_{1-x}$O probed by optical absorption and photoluminescence at high pressure

V. Marín-Borrás, J. Ruiz-Fuertes, A. Segura. +1

The appearance of segregated wurtzite Mg${}_x$Zn${}_{1-x}$O with low Mg content in thin films with $x>0.3$ affected by phase separation, cannot be reliably probed with crystallographic…
