The Formation of Nanodimensional Structures on the Surface of p-CdTe Crystals Exposed to a Single Radiation Pulse from a Ruby Laser

The formation of nanodimensional structures on the surface of p-CdTe crystals has been studied as a function of the radiation-power density of a laser under a single irradiation dose. The best conditions for laser irradiation of the crystals are found. Under these conditions, a homogeneous structure...

Description
Summary:The formation of nanodimensional structures on the surface of p-CdTe crystals has been studied as a function of the radiation-power density of a laser under a single irradiation dose. The best conditions for laser irradiation of the crystals are found. Under these conditions, a homogeneous structure with a period of 100 nm is formed. The lateral size of the structure is {approx}(19-20) nm, and the average height is {approx}(3.40-9.38) nm. It is found that periodicity manifests itself clearly in one crystallography direction.
