Improving the efficiency of photopiezoelectric induction acoustic waves in semi-insulating single crystals of gallium arsenide
The work is devoted to the analysis of the influence of acoustic losses on the efficiency of inducing resonant acoustic waves in single-crystal gallium arsenide plastids using infrared light pulses. It is established that the amplitude of the excited mechanical vibrations depends on the magnitude and position of the internal friction in the crystal on the temperature scale due to acousto-electronic relaxation. Recommendations on the choice of the element of the alloying admixture of gallium arsenide are formulated. Keywords: optical absorption, piezoelectric effect, relaxation, optical pulses.
