abstract

Generation of the electronic waves with high degree of coherence becomes a physical reason for developing holographic electronic microscopy with high resolution and creating the technology of holography for low energies. This effect opens an opportunity to design new tools for observation of the nanometer scale objects without destruction. The general picture can be considered in the approximation of the steady-state wave function. The outgoing wave is described by the amplitude slowly varying along the trajectory. Quantum formulation of photodetachment of a negative ion as the steady-state process is equivalent the inhomogeneous Schrödinger equation. Its solution can be expressed in terms of the Green's function. The exact expression for the Green's three-dimensional function is known in two cases: homogeneous electric field and the Coulomb field. The detailed picture for distribution of photocurrent in a homogeneous field demonstrates the advantages of the quantum theory approach. We found the repulsive Coulomb field is more effective for extension the area of the interference pattern at a small distance from an ion.
