Control of Polarization and Polar Helicity in BiFeO3 by Epitaxial Strain and Interfacial Chemistry
Advanced Functional Materials, EarlyView.In BiFeO3 thin films, the interplay of interfacial chemistry, electrostatics, and epitaxial strain is engineered to stabilize homohelicity in polarization textures at the domain scale. The synergistic use of a Bi2O2‐terminated Aurivillius buffer layer and a highly anisotropic compressive epitaxial strain offers new routes to control the polar‐texture ...

Semiconductor Laser Spectrometry
Analytical Sciences, 1993 A semiconductor laser is more compact and less expensive than a conventional laser. Therefore, scientists prefer to use this light source in analytical spectroscopy. However, the emitting wavelength of the semiconductor laser is located in the near-infrared or deep-red region. Only a limited number of compounds are fluorescent in these spectral regions;

Advanced Functional Materials, EarlyView.In MOCVD MoS2 memristors, a current compliance‐regulated Ag filament mechanism is revealed. The filament ruptures spontaneously during volatile switching, while subsequent growth proceeds vertically through the MoS2 layers and then laterally along the van der Waals gaps during nonvolatile switching.
