Surface damage of CdTe produced during sample preparation, and determination of dislocation types near microhardness indentations

Cathodoluminescence imaging of microindented {111} CdTe

“…Finally, we found that the indentation surface area is nearly proportional to the applied load, indicating that, whatever is the applied load, dislocation equilibrium is reached at the end of the experiment. [3,8,9]. It has to be pointed out that, contrary to GaAs [3], we found that the indent figure was independent of the nature of the indented face.…”

“…Etch-pits on the {111} Te face of a p type specimen revealed that the rosette developed after room temperature microindentation exhibited three-fold symmetry [8]. Each [8] to conclude that 'Iè(g) and Cd(g) dislocations were in the long and the short arm respectively.…”

Each [8] to conclude that 'Iè(g) and Cd(g) dislocations were in the long and the short arm respectively. The higher velocity of the Th(g) dislocation was in agreement with previous results obtained on CdTë samples [12,13], but not with the conclusions drawn from the model of Hirsch et al [3].…”

“…InSb [6,7], CdTe [8,9] and CdHgTb [9], to study the deformation mechanisms around microindentations, or to discriminate the fastest dislocation between the A(g) and B(g) type. The investigations were made either by etching [1,3,8,9], or by transmission electron microscopy [2, 4, 5], or by X-ray transmission topography [6,7].…”
