Phonon Amplification via Transparent PbZrO<sub>3</sub> Layer on Top of SrRuO<sub>3</sub>/SrTiO<sub>3</sub> Heterostructures
By growing PbZrO<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</inf> with two different thicknesses on the SrRuO<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</inf>/SrTiO<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</inf> heterojunction and conducting femtosecond pump-probe experiments, we observed a 3.52- fold amplification of coherent acoustic phonons oscillations in SrTiO<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</inf> substrate via thermoelastic stress.
