Influence of the dielectric matrix on 2D tunnel bifurcations under external electric field conditions

The article theoretically investigates the influence of temperature, external electric field and dielectric matrix on 2D tunnel bifurcations in a system of AFM/STM - metallic QD or in a quantum molecule. The article also shows a phase diagram compiled to diplay the tunnel mode changes for above-mentioned controlling parameters. It has been revealed, that the impact of 2D tunnel bifurcations can be observed for experimentally realizable values of relative dielectric permittivity of the heat - bath matrix.
