Characterization and control of ZnGeN2 cation lattice ordering

11 Jan 2017 Blanton Eric W. He Keliang Shan Jie Kash Kathleen

ZnGeN2 and other heterovalent ternary semiconductors have important potential applications in optoelectronics, but ordering of the cation sublattice, which can affect the band gap, lattice parameters, and phonons, is not yet well understood. Here the effects of growth and processing conditions on the ordering of the ZnGeN2 cation sublattice were investigated using x-ray diffraction and Raman spectroscopy... (read more)
