Abstract

Stepped semiconductor substrates can serve as a template for growing metal films with a corrugated structure at the nanoscale. The corrugation modulates the electron motion and thus modifies the electronic properties of the system. This work is a study of corrugated films of Ag and Pb using angle-resolved photoemission. Our measurements show that the valence electrons form coherent grating cavity modes defined by the corrugation geometry and the photoemission patterns are governed by quantum interference.
