Efficient Extraction of Hot Carriers in Perovskite Quantum Dot through Building State Coupled Complex
Yusheng Li, Junke Jiang, Dandan Wang +12
Utilizing hot carriers is the crucial approach for solar cell to exceed the thermodynamic detailed balance limit, yet effective extraction of hot carriers in absorber materials via…
Surface Acoustic Wave induced modulation of tunneling magnetoresistance in magnetic tunnel junctions
Dhritiman Bhattacharya, Peng Sheng, Md Ahsanul Abeed +6
We show that a surface acoustic wave (SAW) applied across the terminals of a magnetic tunnel junction (MTJ) decreases both the (time-averaged) parallel and antiparallel resistances…
Determination of spin-orbit torques by thickness-dependent spin-orbit torque FMR measurement
Hongshi Li, Mahdi Jamali, Delin Zhang +2
Current induced spin-orbit torques (SOTs) in Fe/Pt bilayers have been investigated utilizing the spin-orbit torque ferromagnetic resonance (SOT-FMR) measurement. Characterization o…
Large field-like torque in amorphous Ru2Sn3 originated from the intrinsic spin Hall effect
