Piezoelectric response to coherent longitudinal and transverse acoustic phonons in a semiconductor Schottky diode
We study the generation of microwave electronic signals by pumping a (311) GaAs Schottky diode with compressive and shear acoustic phonons, generated by femtosecond optical excitation of an Al _lm transducer and mode conversion at the Al-GaAs interface. They propagate through the substrate and arriv...
