Principles of Photon Echo Formation on Special Exciton States in Thin Textured Films at Room Temperature

Аннотация

A way of obtaining new thin-film materials for forming photon echoes at room temperature on special exciton states in thin textured films obtained via magnetron sputtering is proposed, along with a model that explains the properties of new states and is associated with the formation of special exciton states. The dependence of the relaxation times of resonant transitions on the size of nanoscale clusters of surface defects is investigated for different film thicknesses and various semiconductor materials. Prospects for using such materials in medical technology are determined.
