“…As we known, lattice constants of many superlattice materials are in the same order of magnitude as electron wavelength, so quantum effect becomes significant in the related works. Research on electron wave propagation through a series of potential barriers, as a fundamental problem of quantum mechanics, is widely applied to study electronic transport properties in synthetic materials, including the electron wave propagation in doped semiconductor superlattice materials with nonlinearity [1,[4][5][6][7][8][9][10][11][12]. Many interesting phenomena are found, such as the localization or superlocalization properties [9,10,[12][13][14][15], resonant tunneling of electron wave [8,12,[16][17][18], multistability in the current-voltage characteristics [7] and chaotic behavior caused by nonlinearity [4,6,[19][20][21][22].…”

Nonlinear Kronig-Penney model has been frequently employed to study transmission problem of electron wave in a nonlinear electrified chain or in a doped semiconductor superlattice. Here from an integral equation we derive a novel exact solution of the problem, which contains a simple nonlinear map connecting transmission coefficient with system parameters. Consequently, we suggest a scheme for manipulating electronic distribution and transmission by adjusting the system parameters. A new effect of quantum coherence is evidenced in the strict expression of transmission coefficient by which for some different system parameters we obtain the similar aperiodic distributions and arbitrary transmission coefficients including the approximate zero transmission and total transmission, and the multiple transmissions. The method based on the concise exact solution can be applied directly to some nonlinear cold atomic systems and a lot of linear Kronig-Penney systems, and also can be extended to investigate electron transport in different discrete nonlinear systems.

Based on the transfer-matrix method, this paper has investigated the electrical transport properties in monolayer and bilayer graphene superlattices modulated by a homogeneous electric field. It is found that the angular range of the transmission probability can be efficiently controlled by the number of barriers. In addition, current density has an oscillatory behavior with respect to external field and Fermi energy. In other words, the current density in monolayer and bilayer graphene superlattices can be controlled by changing either the external field or the Fermi energy. Meanwhile, in the bilayer system unlike monolayer structure the value of current density can be zero. So, for designing electronic devices, bilayer graphene is more efficient.
