Quantum size effect observed during the small-angle reflection of an electron beam incident onto a single-crystal film with allowance for the average internal lattice potential

Abstract

Analytical formulas are derived and used to perform calculations. The solution to the problem of the quantum size effect arising when a moderate- or high-energy electron beam is reflected from a thin single-crystal film at a small glancing angle of incident electrons is graphically illustrated. The average internal potential of the crystal lattice of the film material is taken into account. Experimental methods for observing the aforementioned effect are proposed.
