Numerical method to optimize the Polar-Azimuthal Orientation of Infrared Superconducting Nanowire Single-Photon Detectors
Numerical method Infrared Superconducting Nanowire
2011/9/2
A novel finite-element method for calculating the illumination-dependence of absorption in three-dimensional nanostructures is presented based on the RF module of the COMSOL software package. This met...
Direct correlation of crystal structure and optical properties in wurtzite/zinc-blende GaAs nanowire heterostructures
Direct correlation of crystal structure optical properties
2010/11/25
A novel method for the direct correlation at the nanoscale of structural and optical properties
of single GaAs nanowires is reported. Nanowires consisting of 100% wurtzite and nanowires presenting zi...
Motion of electrons can influence their spins through a fundamental effect called spin-orbit interaction. This interaction provides a way to electrically control spins and as such lies at the foundati...
AC square-wave, sawtooth-wave, and triangle-wave fields driven adiabatic quantum pumps in nanowire structures
AC square-wave sawtooth-wave triangle-wave fields driven adiabatic quantum pumps
2010/11/18
A dc current can be pumped through a nanostructure by two out-of-phase ac driving fields.
In this approach, we explore the pumped current properties driven by square-wave, sawtoothwave,
and triangle...
