Abstract

The SEM EBIC (or charge collection) method using a surface Schottky barrier was applied to GaP specimens to obtain dark spot micrographs revealing dislocations present in the specimens. We describe the experimental procedures and electron probe parameters necessary to obtain such micrographs for specimens ranging from LEC substrate material to doped and undoped VPE layers, and compare the results obtained with analogous results for the SEM CL method. A one-to-one correspondence between the dark spots in corresponding EBIC and CL micrographs was demonstrated. Factors affecting the spatial resolution of the micrographs are discussed; a best resolution of ∼ 1μm was obtained.
