Nonlinear response of a double-well nanostructure with electron-electron interaction

Nonresonant transparency channels of a two-barrier nanosystem in an electromagnetic field with an arbitrary strength

“…As is known, the theory of the transport of electron fluxes through resonant tunneling structures was developed in detail in the small signal approximation [6][7][8][9]. The dependences of the properties of ballistic electron transport through resonant tunneling nano systems on the strength of the electric component of the electromagnetic field were analyzed in [10][11][12].…”

“…Here, we introduce the convenient compact notation (8) with the obvious physical meaning: α is the kinetic energy of the electron with the quasimomentum k a and β is the potential energy of the interaction of the electron with the field of strength Ᏹ divided by the field energy Ω.…”

Electronic Conductivity in Open Cylindrical Two-Barrier Symmetric Resonance Tunnel Structure

“…(15). They are equivalent to the system of eight linear inhomogeneous equations, determining all eight unknown coefficients (A F (z, t) wave functions.…”

“…The mathematical complication is that in the majority of theoretical papers [10][11][12][13][14][15][16][17] simplified models of nano-systems (mainly the plane ones) are used. These models are based at the δ-barrier approximation of RTS rectangular potential barriers.…”

Dynamic conductivity of symmetric three-barrier plane nanosystem in constant electric field

“…In references [9][10][11][12][13][14][15], mainly within the model of unitary effective mass and δ-like potential barriers, there have been developed the theoretical approaches to the calculation of active conductivity of electrons in open RTS. Recently, in references [16,17] it was shown that δ-barrier model with unitary electron effective yields too rough magnitudes of resonance widths of quasistationary states (ten times bigger) relatively to the realistic model of rectangular potential barriers with different effective masses of quasiparticle in different pars of RTS.…”
