TRANSPORT AND DEPOSITION OF METALLIC IONS IN ALPHA-QUARTZ

Abstract

Four distinct types of optical decorations resulted from manipulating a negatively charged microprobe over the (0 01) face of a silver back d quartz crystal at temperatures between 300-573 C. The most prominent o these decorations was the formation of conducting me allic platelets on the basal plane of the crystal in the vicinity of the probe. These platelets were of uniform thickness, about .4 of a micron, with surface areas ranging up to the dimensions of the anode. Geometric patterns showing the six-fold symmetry of the basal plane were observed to form, at or near the cry tal s rface, within a fraction of a second upon the application of a negative probe to the (0001) face. Probe currents, both axial and equatorial, were found to be thermally activ ted with energies of 38 Kcal/Mole for conduction not involving the transport of silver ions. (Author)
