A resistive dynamic evaporator for multicomponent materials

Abstract

A resistive dynamic evaporator designed to produce thin films of multicomponent materials is described. The evaporator consists of a hollow vessel 19 mm in diameter and 24 mm high and a conical gate coaxially inserted into the cavity, as well as a wire heating element. When the pressing force of the vapors of the evaporated material begins to exceed the force that presses the gate to the end surface of the vessel, the latter is depressurized; otherwise, it resumes its initial state. Using cadmium telluride as an example, it is shown that these design features provide the formation of high-quality thin films of multicomponent materials.
