A METHOD FOR ELECTROCUTTING SINGLE CRYSTALS OF METALS AND ELECTROPOLISHING THE EXPOSED CRYSTALLINE FACE.
AIR FORCE CAMBRIDGE RESEARCH LABS L G HANSCOM FIELD MASS
In order to minimize the introduction of physical defects into soft crystals during cutting or slicing operations, a technique has been developed for electrocutting and electro polishing ingots where electrochemical dissolution is used. Copper crystals were masked to expose the area to be cut and, using an electrolyte of copper dihydrogen phosphate, anodic dissolution exposed the desired surface. The resulting surface was electropolished in order to expose the desired face for later use as an epitaxial substrate. Author
