Decoupled modulation of the degree of optical polarization and emission wavelength in far-UVC-LEDs: A staggered quantum wells strategy
The inherently poor light extraction efficiency severely limits the application of AlGaN-based far-ultraviolet-C (far-UVC) light emitting diodes (LEDs) (<240 nm). This originates from the ultra...
Role of spatiotemporal nonuniformities in laser-induced magnetization precession damping
Laser-induced magnetization precession measurements in ferromagnets often reveal an anomalous decrease in damping time near a field-induced second-order spin-orientation transition, a behavior that ca...
Analysis of native oxides grown on single-crystal CdTe and MgCdTe
Over the course of CdTe photovoltaics development, many refinements to the device stack have been made. One area of current interest is the back contact interface, where surface passivation is critica...
An electrically isolated Josephson junction array as a tunable metamaterial
We report low-temperature microwave transmission measurements on a superconducting metamaterial composed of an electrically isolated two-dimensional Josephson junction (JJ) array. Each plaquette, whic...
Ultrafast vibrational dynamics: An impulsively stimulated resonance Raman perspective
Accessing excited-state vibrations is crucial to elucidate physical and chemical properties of photoreactive molecules and solids. Time-resolved resonance Raman spectroscopy provides unique vibrationa...
