Thermal stability of Al/AlGaAs and Al/GaAs/AlGaAs (MBE) Schottky barriers
Electronics Letters, 1993 Outstanding stability has been observed in Al/Al/sub x/Ga/sub 1-x/As and Al/GaAs/Al/sub x/Ga/sub 1-x/As (x=0.25) Schottky barriers prepared by depositing Al in situ by MBE on annealing up to 400 degrees C. Conventionally evaporated barriers have been fabricated and compared with epitaxial ones.

Advanced Optical Materials, Volume 14, Issue 12, 25 March 2026.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 ...

Advanced Science, Volume 13, Issue 13, 3 March 2026.A DUV‐VCSEL strategy featuring the nanometer‐class control of the cavity length is proposed in the DUV optoelectronic framework based on GaN templates. After the sapphire removal, a self‐terminated etching technology is developed, whereby the cavity length can be accurately determined by epitaxy instead of the fabrication process. As such, a record low

Journal of Biophotonics, Volume 19, Issue 3, March 2026.Spinal cord injuries (SCI) cause severe motor and sensory deficits, with limited treatment options. This study demonstrates that early application of photobiomodulation (PBM) can protect spinal cord tissue and accelerate functional recovery in a preclinical model, which integrates biomechanical analysis with histomorphological characteristics of the ...
