Advanced Materials Technologies, EarlyView.Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Band Gaps and Waveguiding in Phoxonic Silicon Crystal Slabs [PDF]
, 2011 We discuss the simultaneous existence of phoxonic, i.e., phononic and photonic, band gaps in a periodic array of holes drilled in a Si membrane. We investigate in detail both the square and the honeycomb lattices. We show that complete phoxonic band gaps

Advanced Science, EarlyView.First‐principles calculations reveal that monolayer In2O${\rm In}_2{\rm O}$ hosts type‐II Dirac fermions near the Fermi level, which split into Weyl points under spin‐orbit coupling. The material exhibits negative and giant magnetoresistance, a pronounced spin Hall effect, and phonon‐mediated superconductivity at 1.5 K, establishing it as a unique ...
