Description

Thermally stimulated exoelectron emission (TSEE) from α alumina single crystals is studied. Polished as well as stamped surfaces present almost identical TSEE effects. Nevertheless a special peak at 4400C appears in the glow curve of stamped samples only. Microscopical observations provide evidence of a relation between the appearance of this peak and fragmentation of crack propagation around the marks made on the surface. (author)
