Effect of Ion Bombardment on the Density of States of Valence Electrons in CdS Films

Аннотация

Cd nanofilms with a thickness of 10–12 Å are obtained by bombarding a CdS surface with Ar⁺ ions. The obtained Cd–CdS nanofilm systems are shown to be promising for creating metal–insulator–semiconductor and semiconductor–insulator–semiconductor heterostructures and forming nanoscale barrier layers and hyperfine ohmic contacts on the semiconductor surface.
