Highly Stable and Non‐Volatile Optoelectronic Synapses for Sensing, Memory, and Computing Enabled by a Deep‐Potential Floating Gate

Advanced Science, EarlyView.
A deep‐potential metal floating gate integrates electrical programming, optical partial erasure, and synaptic weight modulation in a MoS2/h‐BN/Au transistor. The device provides a 97.6 V memory window, retention beyond 3000 s, endurance over 1600 cycles, and reproducible operation after 200 days of ambient storage.

Multi-dimensional Imaging in the Terahertz Regime for Theranostic Applications

, 2017
We demonstrate a novel terahertz radiation-based joint thermal-hyperspectral imaging method for theranostic applications. Hyperspectral imaging of a drug formulation was realized in the stratum granulosum of skin, in the presence of plasmonically heated ...

Terahertz metasurface based on vanadium dioxide for realizing CNOT logic gate and tunable vortex beams

Results in Physics
Independent phase control of circularly polarized light on a single metasurface is highly desirable for terahertz applications. However, most metasurfaces reported suffer from two critical limitations: the lack of dynamic tunability and narrow ...

Mode‐Resolved Phonon Dynamics Under Chemical Pressure in SnTe Thermoelectrics

Advanced Science, EarlyView.
Chemical pressure reshapes low‐energy optical phonons in SnTe, altering their dispersion and scattering with heat‐carrying acoustic modes. Positive and negative pressure states modify phonon frequencies and lifetimes in distinct ways, revealing how mode‐selective lattice perturbations regulate acoustic–optical interactions and suppress lattice thermal ...
