描述.This book studies electron resonant tunneling in two- and three-dimensional quantum waveguides of variable cross-sections in the time-independent approach. Mathematical models are suggested for the resonant tunneling and develop asymptotic and numerical approaches for investigating the models. Also, schemes are presented for several electronics devices based on the phenomenon of resonant tunneling. Compared to its first edition, this book includes four new chapters, redistributes the content between chapters and modifies the estimates of the remainders in the asymptotics of resonant tunneling characteristics. The book is addressed to mathematicians, physicists, and engineers interested in waveguide theory and its applications in electronics..

Asymptotic and Numerical Studies of Resonant Tunneling in 2D-Waveguides for Electrons of Small Ener resonant tunneling is discussed for electrons with energy between the first and the second thresholds, so only one incoming wave and one outgoing wave can propagate in every outlet of the waveguide; in other words, we deal with electrons of small energy. There are no external fields. We derive asym

Resonant Tunneling in 2D-Waveguides with Several Resonators, shape and are spaced from each other by equal distances. Parts of the waveguide between two neighboring narrows play the role of resonators. The wave function of a free electron satisfies the Dirichlet boundary value problem for the Helmholtz equation in the waveguide. Near a simple eigenvalue of t

Resonant Tunneling of High-Energy Electrons in 2,-Waveguides,the homogeneous Dirichlet boundary condition. The energy of electrons (spectral parameter) may be rather high, i.e. any (fixed) number of waves can propagate in the strip far from the narrows. The spectral parameter varies in the vicinity of a degenerate eigenvalue of the resonator and is separated

Numerical Simulation of High Energy Electron Transport,ical simulations have shown that the resonances are of Fano type. The form of the transmission probability curve is conditioned by interference of the quantum states into which the electron wave is scattered by the narrows.The suggested interference model makes possible to find the resonance paramet

Asymptotics of Resonant Tunneling in 3D Waveguides for Electrons of Small Energy,e boundary of the waveguide is assumed to be smooth. The electron motion is described by the Helmholtz equation. The electron energy is supposed to be between the first and the second thresholds. We generalize and implement the asymptotic approach developed in Chap. .. The basic results are presente

Resonant Tunneling in 2D Waveguides in Magnetic Field,ns in electronics. In particular, in the presence of a magnetic field, the tunneling phenomenon is feasible for producing spin-polarized electron flows consisting of electrons with spins of the same direction. In Chap. ., we describe magnetic field sensors based on resonant tunneling in magnetic fie

Unlike the transistors and the sensors, the switch has no relation to the phenomenon of resonant tunneling. However, the scattering matrix needed for analyzing the
