Mechanical vibration-induced suppression of transverse acoustic phonons in silicon due to Akhiezer damping
Thermoelectric modules that utilize waste heat from machinery are inevitably exposed to mechanical vibrations. Here, we investigated the effects of mechanically induced phonon anharmonicity on Akhiezer damping with three different vibrational modes: Lamé, square extensional, and width extensional mo...
