Electron interferometry and holography of electrostatic fields: Fundamental and applicative aspects

Abstract

Two different applications of matter wave interferometry are presented and discussed. The first is aimed at investigating the interference fringe shift generated by a macroscopic electric dipole. This experiment represents the electrostatic analogue of the Aharonov-Bohm effect involving time-dependent scalar potentials. The second concerns a practical application of the electron holography technique to the mapping of the total field associated with reverse biased p-n junctions.
