Magneto-gyrotropic effects in semiconductor quantum wells (review)

, 2008
Magneto-gyrotropic photogalvanic effects in quantum wells are reviewed. We discuss experimental data, results of phenomenological analysis and microscopic models of these effects. The current flow is driven by spin-dependent scattering in low-dimensional

Local Thermal Conductivity Patterning in Rotating Lattice Crystals of Anisotropic Sb2S3

Advanced Functional Materials, EarlyView.
Microscale control of thermal conductivity in Sb2S3 is demonstrated via laser‐induced rotating lattice crystals. Thermal conductivity imaging reveals marked thermal transport anisotropy, with the c axis featuring amorphous‐like transport, whereas in‐plane directions (a, b) exhibit 3.5x and 1.7x larger thermal conductivity.

The Dynamics of Interfacial Trap States in High‐Detectivity Near‐Infrared Photomultiplication Organic Photodetectors

Advanced Functional Materials, EarlyView.
Photomultiplication organic photodetectors (PM OPDs) are an attractive strategy for health‐monitoring. Here, PM‐OPDs are reported with a specific detectivity of 5.7 × 1012 Jones and external quantum efficiency values of 3500% under −10 V. The dynamics of carrier trapping in these devices are elucidated through trap selective spectroscopical techniques.

Reducing the critical switching current in nanoscale spin valves

, 2004
The current induced magnetization reversal in nanoscale spin valves is a potential alternative to magnetic field switching in magnetic memory devices. We show that the critical switching current can be decreased by an order of magnitude by strategically ...

Analysis of the Electrochemical Stability of Sulfide Solid Electrolyte Dry Films for Improved Dry‐Processed Solid‐State Batteries

Advanced Functional Materials, EarlyView.
An adapted processing for solvent‐free argyrodite solid electrolyte films based on insights into degradation mechanisms of the widely used binder polytetrafluoroethylene is presented. By adapting the dry film processing, long‐term cycling in Si||NMC pouch cells is demonstrated over more than 1000 cycles with a capacity retention of more than 80%, and ...

One-way Quantum Key Distribution System based on Planar Lightwave Circuits

, 2006
We developed a one-way quantum key distribution (QKD) system based upon a planar lightwave circuit (PLC) interferometer. This interferometer is expected to be free from the backscattering inherent in commercially available two-way QKD systems and phase ...
