Light Figures of Single Crystals of Tetragonal Tin and the Determination of Their Crystal Orientations by the Light-Figure Method, Part III. Orientation Determination by the Light-Figure Method

Mikio Yamamoto and Jiro Watanabé


Abstract:

The procedure for a perfect, accurate and rapid determination of orientations of tetragonal tin single crystals by the use of light figures has been worked out. Full accounts are given of necessary geometrical relationships, etching technique, measurable ranges and kinds of angles, stereographic representation of crystal orientations, and the accuracy with reference to various actual examples. It is shown that perfect determination of crystal orientations can be made with an accuracy well within 1° by the use of the {001}, {100} and {101} light figures produced by etching with concentrated aqua regia.
