Dark and Light Pits in Bismuth Crystals

Shuichi Otake, Shigetoshi Koike and Yoshinobu Motohashi

(Received June 28, 1973)

In our previous paper, dislocation etch pits on various crystal planes of bismuth formed by the etchant of Lovell and Wernick were shown to appear as two different kinds of pits, dark and light, as observed by an optical microscope. Kinds of dislocations possible corresponding to these etch pits are investigated, and it is shown that the dark and light pits correspond to screw and edge dislocations, respectively. Suggestions are made for the mechanism for the occurrence of these different kinds of pits.
