Advanced Science, EarlyView.A thermally programmable two‐port non‐Hermitian acoustic metastructure is presented, where temperature acts as a non‐geometric tuning variable. Thermal modulation reconfigures impedance matching and loss‐leakage coupling, enabling exceptional‐point driven, broadband, and direction‐dependent sound absorption without requiring geometric reconfiguration ...

Robust C–V Ratio Technique for Profiling Defects in Proton‐Irradiated 4H‐SiC
Advanced Electronic Materials, EarlyView.A noise‐robust C–V ratio technique is introduced to profile radiation‐induced defects in proton‐irradiated 4H‐SiC Schottky diodes. By using analytical capacitance ratios instead of numerical differentiation, the method directly extracts trap‐density and effective trap‐energy profiles at room temperature.
