Abstract

AbstractThe growth of Si‐doped 2H‐AlN thin films by plasma‐induced molecular‐beam epitaxy is reported. We have found that Si positively affects the epitaxy being an effective surfactant for AlN growth with a remarkable impact on the crystal quality. It was also observed that heavy doping conditions result in the volume segregation of Si at the threading dislocation network and in the formation of an amorphous (AlO)(SiO)N cap layer caused by post‐growth surface oxidation of the accumulated Al and segregated Si.
