DNA-based tunable THz oscillator
A. V. Malyshev, V. A. Malyshev, F. Dominguez-Adame
The intrinsic double helix conformation of the DNA strands is known to be the key ingredient of control of the electric current through the DNA by the perpendicular (gate) electric…
Energy transfer processes in Er-doped SiO2 sensitized with Si nanocrystals
I. Izeddin, D. Timmerman, T. Gregorkiewicz +4
We present a high-resolution photoluminescence study of Er-doped SiO2 sensitized with Si nanocrystals (Si NCs). Emission bands originating from recombination of excitons confined i…
Impact ionization fronts in semiconductors: superfast propagation due to "nonlocalized" preionization
Pavel Rodin, Andey Minarsky, Igor Grekhov
We discuss a new mode of ionization front passage in semiconductor structures. The front of avalanche ionization propagates into an intrinsic semiconductor with a constant electric…
Giant Magnetoelectric Effect via Strain-Induced Spin-Reorientation Transitions in Ferromagnetic Films
N. A. Pertsev
It is shown theoretically that a giant magnetoelectric susceptibility exceeding 10^-6 s/m may be achieved in the ferromagnetic/ferroelectric epitaxial systems via the magnetization…
STM images of sub-surface Mn atoms in GaAs: evidence of hybridization of surface and impurity states
J. -M. Jancu, J. -Ch. Girard, M. Nestoklon +3
We prove that scanning tunneling microscopy (STM) images of sub-surface Mn atoms in GaAs are formed by hybridization of the impurity state with intrinsic surface states. They canno…
Intrinsic electric polarization in spin-orbit coupled semiconductor heterostructures
A. V. Rodina, A. Yu. Alekseev
We present Maxwell equations with source terms for the electromagnetic field interacting with a moving electron in a spin-orbit coupled semiconductor heterostructure. We start with…
