Measurement of threading dislocation densities in GaN by wet chemical etching
We demonstrate a technique based on wet chemical etching that enables quick and accurate evaluation of edge- and screw/mixed-type threading dislocations (TDs) in GaN. Large and small etch pits are formed by phosphoric acid [...]

A fracture criterion for gallium arsenide wafers
The fracture of single crystal gallium arsenide (GaAs) semi-conducting wafers was studied. Prismatic beam specimens, cut at different crystallographic orientations from thin wafers, were loaded to failure in four-point bending. Fracture in these crystals occurred predominantly on the [...]
