Information on the crystal orientation of GaP single crystals has been obtained from the light emitting pattern around a point contact electrode; the light emission shows a threefold pattern which reflects a symmetry of the (111) surface of GaP. The result coincides with the reflectogram pattern observed by the light-figure method. This method, as is termed “Schottky Probe Method”, is simple compared with the other methods to find the crystal plane orientations.
