WebJul 18, 2024 · A design paradigm of topology has recently emerged to manipulate the flow of phonons. At its heart lies a topological transition to a nontrivial state with exotic properties. This framework has been limited to linear lattice dynamics so far. WebPhononic General Information. Description. Developer of thermoelectric chips designed to offer an alternative to compressor technology and traditional methods of refrigeration.

WebThe PnC structures were fabricated by etching a square array of cylindrical air holes in a 10 lm thick free-standing silicon plate using a CMOS-compatible process. Preliminary experimental results show that the performance of the PnC resonators in terms of resonant frequency, Q factor, and insertion loss (IL) is highly dependent on r0.
