Real-valued gain enabled higher-order exceptional point under anti-parity-time symmetry
Non-Hermitian systems exhibit dramatically enhanced spectral sensitivity to perturbations near higher-order exceptional points (HOEPs), with response strength scaling exponentially with the order of t...
Enhancing vibration isolation and energy harvesting via a quasi-zero stiffness electromagnetic system
Vibration-related issues are common causes of failure in precision machines, and energy harvesting techniques can help mitigate harmful vibrations and recycle waste energy. This Letter introduces an e...
Optimization of GaInP absorber design for indoor photovoltaic conversion efficiency above 40%
Indoor photovoltaics (IPV) is a key technology for powering low-energy electronics, particularly Internet of Things devices, where wired power or frequent battery replacements are impractical. IPV cel...
Pressure-induced phase transitions and broadband photoresponse in layered 2D MoO3
This work investigates the pressure-dependent structural evolution and optoelectronic behavior of MoO3 under high pressure to 37.8 GPa, combining in situ Raman spectroscopy, x-ray photoelectron spectr...
Reduction in surface defects on red-emitting InGaN quantum wells by using vicinal GaN (0001) surfaces
This study demonstrates a substantial reduction in surface defects on red-emitting InGaN quantum wells (QWs) by using vicinal GaN (0001) surfaces. Red InGaN QWs are grown on GaN on sapphire (0001) sub...
Gate-Voltage modulated spin caloritronics in Fe/Cr-doped Janus MoSeTe nanoribbons
Conventional thermoelectric conversion based on charge transport faces significant challenges due to inherent limitations, such as a low power factor, inevitable Joule heating, and high thermal conduc...
Acoustic rainbow trapping effect of double corner states in higher-order topological insulators
Higher-order topological insulators are a type of topological state of matter, which break the traditional bulk-edge correspondence principle. At the same time, the concept of higher-order topological...
