Generation and coherent control of terahertz acoustic phonons in superlattices of perovskite oxides

We utilized transmission-type pump–probe technique to investigate coherent acoustic phonons in the superlattices of perovskite oxides such as SrIrO _3 /SrTiO _3 and SrRuO _3 /SrTiO _3 . Because the films in the superlattices are of high-quality and their thicknesses are only several monolayers, quas...
