Photoelastic properties of zinc-blende (AlGa)N in the UV: picosecond ultrasonic studies

Picosecond ultrasonics was used to study the photoelastic properties of zinc-blende (cubic) c-AlₓGa₁₋ₓN with x around 0.5 The velocities for longitudinal sound in the alloys were measured using ultrafast UV pump-probe experiments with (AlGa)N membranes. Strong Brillouin oscillations wer...
