Dissipative Tunneling of Electrons in Vertically Coupled Double Asymmetric InAs/GaAs(001) Quantum Dots

Features of tunneling current-voltage characteristics in dielectric films with Ni, Fe and Co nanoparticles, investigated by conductive AFM and within the framework of the theory of 1D-dissipative tunneling

“…The maximum on tunneling I-V curves for Au nanoparticles in SiO 2 films [1] A series of nonequidistant peaks in the tunneling I-V curve of InAs/GaAs(001) quantum dots [1,2] 2D-bifurcations on the tunnel I-V curves of the Au nanoparticles-arrays in SiO 2 films [1] 2D bifurcations on the field dependence of the photocurrent of a p-i-n diode with double asymmetric InAs/GaAs(001) quantum dots [3] one-instanton semiclassical approximation in a model double-well oscillatory potential in the framework of the science of quantum tunneling with dissipation [1,2,[4][5][6][7][9][10][11][12][13][14][15][16][17][18][19][20] under conditions of an external electric field, and experimentally (by the method of conducting AFM). The experimental results are interpreted on the basis of the one-dimensional dissipative theory of tunneling in the limit of weak dissipation [1,4,[6][7][8], and a qualitative comparison is made between the experimental and theoretical results (individual tunneling I-V curves and the field dependence of the probability of 1D dissipative tunneling).…”

“…Experimental observation of theoretically predicted macroscopic quantum effects of dissipative tunneling in lowdimensional systems (see, for example, [1][2][3]) is one of the current interest problems of modern condensed matter physics [1,4,5], since it allows both to study fundamental observable macroscopically realizable quantum effects and to develop the innovative nanoelectronics and nanophotonics devices with controlled characteristics (optical THz-IR converters, tunneling photodiodes, etc.). In the last decade, the authors of this work have experimentally observed effects due to dissipative tunneling of electrons in a number of artificial nanoscale systems.…”
