Abstract
Semi-conducting material is prepared by subjecting a solid body of germanium and silicon to an alternating fractional fusion process i.e. to a process in which a molten zone is caused to traverse the body, through a distance appreciably greater than the thickness of the zone, substantially an equal number of times in opposite directions. The initial solid body may be made by quenching a melt of silicon and germanium or by forming a compact mass from a mixture of the powdered elements. The mean composition of the body may be altered during the treatment by cutting-off one end of the body at a time when this end contains a relatively large concentration of one or other of the components or by adding one component to the molten zone during its passage through the body.
