Solution‐Processed Spin‐Polarized Light‐Emitting Diodes of Colloidal Quantum Wells and Magnetic Nanoparticles

Advanced Optical Materials, EarlyView.
All‐solution‐processed spin‐LEDs based on colloidal Fe3O4 nanoparticles and CdSe/CdZnS core/shell CQWs that allows for polarization modulation of electroluminescence are fabricated. With these devices, electrical injection of spin‐polarized carriers from the Fe3O4 nanoparticle layer into the CdSe/CdZnS CQWs is demonstrated, realizing circularly ...

Bay‐functionalized [7]Helicene Bilayer Nanographenes

Advanced Optical Materials, EarlyView.
Bay‐functionalized [7]helical bilayer nanographenes are synthesized via a scalable, modular strategy enabling late‐stage diversification. Tailored methoxy, diketone, and phenazine substitutions precisely tune redox, photophysical, and chiroptical properties, delivering strong electronic circular dichroism and bright circularly polarized luminescence ...

Experimental Evidence of Free Carrier Generation in 2D Hybrid Organic–Inorganic Perovskites

Advanced Optical Materials, EarlyView.
ABSTRACT Despite the significant potential of 2D hybrid organic–inorganic perovskites (2DHOIPs) for high‐efficiency optoelectronics application‐comparable to their 3D counterparts, the fundamental carrier photogeneration remains unclear. In contrast to conventional ultrafast optical property characterization, we use ultrafast photocurrent spectroscopy ...

Optical control of RKKY coupling and perpendicular magnetic anisotropy in a synthetic antiferromagnet

Nature Communications
Synthetic antiferromagnetics (SAF) provide an excellent platform for antiferromagnetic spintronics. Recently, the voltage-control of the Ruderman–Kittel–Kasuya–Yosida (RKKY) interaction in SAFs was studied experimentally.

Spintronics

III-Vs Review, 2003
AbstractRecent successes by a Nottingham University group includes the growth of GaMnAs material with world record Curie temperatures, and ferromagnetic TiCoO2 and GaMnN which shows ferromagnetism at room temperature. A characteristic of the GaMnAs layers grown by the group is their low resistivity that is accompanied by very weak high field magneto ...
