Ep. Pokatilov et al., INTERACTION HAMILTONIAN BETWEEN AN ELECTRON AND POLAR SURFACE VIBRATIONS IN A SYMMETRICAL 3-LAYER STRUCTURE, Physical review. B, Condensed matter, 47(24), 1993, pp. 16597-16600
The Hamiltonian of the interaction between an electron and surface vib
rations for a three-layer symmetrical structure is obtained. In the li
miting case of infinite outer-layer thickness, the known results by Mo
ri and Ando are reproduced.
