On the formation of nanostructures on a CdTe surface, stimulated by surface acoustic waves under nanosecond laser irradiation
- National Academy of Sciences of Ukraine, Lashkaryov Institute of Semiconductors Physics (Ukraine)
The formation of nanoscale structures in the unirradiated part of a p-CdTe crystal surface irradiated by a nanosecond ruby laser is revealed and investigated. It is shown that their formation is caused by the effect of the long-range action of a laser pulse with an intensity of I = 20 MW/cm{sup 2}. Nanoscale-structure formation is explained by the influence of the pressure gradient of the surface acoustic wave, in particular, within the “vacancy-pump” mechanism on the surface.
