The effect of a dielectric matrix on tunnel volt-ampere characteristics in quantum dots under conditions of an external electric field

The article considers a 1D-dissipative tunneling model for structures with quantum dots in system of joint AFM/STM in external electric field. It is revealed, that the influence of a local mode of a heat-bath on the 1D-dissipative tunnel probability leads to occurence of two peaks in corresponding dependence from intensity of electric field; one of this peaks is unstable (for case of symmetric double - well oscillator potential), and another additional peak is a stable one. Obtained theoretical dependence qualitatively corresponds to experimental VAC for the AFM cantilever contact to surface of QD from InAs.
