Non-interferometric measurement of geometric phase through stimulated second harmonic generation
The geometric phase (GP), arising from the evolution of states like polarization on the Poincaré sphere, is conventionally measured using interferometry. However, the interferometric techniques often...
Pt-based multilayers toward energy-efficient spin–orbit torque devices
The 5d transition metal Pt is widely recognized as a spin Hall material for generating spin–orbit torques (SOTs) in Pt/ferromagnetic (FM) heterostructures. Despite its low resistivity, it exhibits a d...
Thin-channel AlGaN/GaN/AlN double heterostructure HEMTs on AlN substrates via hot-wall MOCVD
III-Nitride high-electron mobility transistors (HEMTs) grown on AlN substrates offer significant advantages for high-power, high-frequency applications due to AlN high thermal conductivity and ultra-w...
Enhanced terahertz metasurface biosensor with reduced substrate effect for trace detection of lung cancer cells
This paper reports an ultrasensitive Terahertz metasurface biosensor with the reduced substrate effect for trace detection of lung cancer cells. By innovatively etching the quartz substrate before gol...
2.87 kV/3.68 mΩ cm2 low forward voltage Ga2O3 vertical SBD with nitrogen-doped protecting ring and mesa termination
In this paper, a vertical Ga2O3 Schottky barrier diode (SBD) with nitrogen (N)-doped protecting ring and mesa termination (NMT-SBD) is fabricated. In addition to the electric field optimization effect...
