Propagation of THz acoustic wave packets in GaN at room temperature

Propagation of THz acoustic wave packets in GaN at room temperature

We use femtosecond laser pulses to generate coherent longitudinal acoustic phonons at frequencies of 1-1.4 THz and study their propagation in GaN-based structures at room temperature. Two InGaN-GaN multiple-quantum-well (MQW) structures separated by a 2.3 μm-thick GaN spacer are used to simultaneous...
