Abstract

The article deals with the discovery of femtosecond signals of self-diffraction and photon echo in a zinc oxide film of 100 nm thickness, consisting of different-sized quantum dots, at room temperature. Experimental results, proving the Autler-Townes effect demonstration on exciton transitions of quantum dots, are obtained.

Keywords: femtosecond photon echo, self-diffraction, zinc oxide film, magnetron sputtering, quantum dots, Autler-Townes effect
