“…An alternative way for getting optimal PZT on transparent electrode is to use film transfer processing [15]. In that case, the optimal PZT stack grown on suitable substrate is transferred to a host substrate following various possible techniques (grinding of the donor substrate [16], etching of sacrificial layer between PZT and the grown substrate [17][18][19][20], laser lift-off [21]). More details about transfer processing can be found in the review paper of Song et al [22].…”
