Strain-induced charge order in overdoped YBCO thin films

In this proposal we want to focus on the evolution of CDWs with strain, investigating our slightly overdoped, strained, YBCO thin films. By combining our transport data with RIXS, representing the most powerful technique for the detection of CDWs, we aim at correlating the characteristics of the charge order to changes in the crystal structure and transport properties at different thicknesses. A successful identification of CDWs in slightly overdoped YBCO would give the first evidence that the critical doping of charge order can be tuned by strain and therefore by geometrical modification of the unit cell.
