Gallium concentration dependence of room-temperature near-bandedge luminescence in n-type ZnO:Ga

T. Makino, Y. Segawa, S. Yoshida +3

We investigated the optical properties of epitaxial \textit{n}-type ZnO films grown on lattice-matched ScAlMgO${}_4$ substrates. As the Ga doping concentration increased up to $6 \ti…
