Characterization of Cs3Sb photocathodes at cryogenic temperatures
We report measurements of quantum efficiency (QE) and mean transverse energy (MTE) from Cs3Sb photocathodes in a wide range of photon energies at both room and cryogenic temperatures. Our measurements...
Strain-driven anisotropic SHG and Raman responses in NbOBr2
Due to the anisotropic structure with broken inversion symmetry, niobium oxide dihalide (NbOBr2) exhibits notable directional and nonlinear optical properties. However, experimental studies on control...
Observation of acoustic spin skyrmion in confined sound field with orbital angular momentum
Topological textures of spin vectors are fundamentally interesting and possess generic features for various vector waves. However, experimental realizations of spin skyrmions are mostly restricted to...
Strain effect on the perpendicular magnetization switching driven by spin–orbit torque
In this study, we investigate the influence of strain on spin–orbit torque and current-induced magnetization switching in Ta/Pt/Co/Ta heterostructures deposited on flexible polyimide substrates. By ap...
Performance enhancement of GaN-based VCSELs by composition-graded structures
The carrier-injection efficiency and confinement within the active region play a crucial role in determining the threshold and slope efficiency of GaN-based vertical-cavity surface-emitting lasers (VC...
Spectral-filtering-induced phase transition in passively mode-locked fiber lasers
We investigate the effect of a tunable spectral filter on the dynamics of a passively mode-locked fiber laser in the anomalous dispersion regime. The results show that noise-like pulse emission evolve...
Mass transfer enhancement in continually replenished aerophilic surfaces
Absorption of gas in liquid media is an important step in applications ranging from environmental remediation to bioreactor design, yet it is often limited by slow interfacial mass transport. Here, we...
