We investigated a mechanism of rectification in diblock oligomer diode molecules that have recently been synthesized and showed a pronounced asymmetry in the measured I-V spectrum. The observed rectification effect is due to the resonant nature of electron transfer in the system and the localization properties of bound state wave functions of resonant states of the tunneling electron interactin...

Simulation and modeling of gate tunneling current for thin-oxide MOSFETs and Double-Gate SOIs are discussed. Guidelines for design of leaky MOS capacitors are proposed. Resonant gate tunneling current in DG SOI is simulated, based on quantum-mechanical models, and shown to be an issue of growing concern.

We study Zener tunneling in two-dimensional photonic lattices and derive, for the case of hexagonal symmetry, the generalized Landau-Zener-Majorana model describing resonant interaction between high-symmetry points of the photonic spectral bands. We demonstrate that this effect can be employed for the generation of Floquet-Bloch modes and verify the model by direct numerical simulations of the ...
