The Growth of Single Crystal of Zinc Selenide

P(論文)ZnSe single crystal is made by the Bridgeman method under high inert gas pressure and its crystallographic characteristics are described. The lattice parameter of grown crystal is 5.667±0.003 Å and the twin structures along the directions are observed. There are two kinds of {111} planes in zinc blend type compounds, one is designated as {111} surfaces or A surfaces and the other as {111} surfaces or B surfaces. Their differences are determined by means of the anomalous dispersion of X-ray and are discussed in relation to etch patterns.departmental bulletin pape
