Chiral‐Induced Spin Selectivity Effect in a 1 nm Thin 1,1′‐Binaphthyl‐2,2′‐diyl Hydrogenphosphate Self‐Assembled Monolayer on Nickel Oxide

Advanced Science, EarlyView.
A self‐assembled monolayer (≈0.9 nm) of an axially chiral binaphthol phosphoric acid derivative on a ferromagnetic Ni/NiOx substrate shows chiral‐induced spin selectivity (CISS) magnetoresistance of 50%–80%. This thermally and chemically robust functional stack shows the way towards practical spintronic devices based on the CISS effect.

Stepwise Engineering of Van der Waals Heterostructures for High Current Density in Light Emitting Devices

Advanced Electronic Materials, EarlyView.
A novel strategy for achieving high current density in van der Waals (vdW) heterostructure‐based light‐emitting devices (LEDs) is proposed. Based on this concept, an LED utilizing a WS2/WSe2 heterostructure was fabricated, achieving a current density of 9.4 × 104 A/cm2.

Electron-photon interaction in resonant tunneling diodes [PDF]

Europhysics Letters (EPL), 1997
We develope a model to describe the transmission coefficient and tunneling current in the presence of photon-electron coupling in a resonant diode. Our model takes into account multiphoton processes as well as the transitions between electronic states with different wave numbers.
