Ultrafast charge-transfer dynamics in Ca${}_2$CuO${}_2$Cl${}_2$ from time-resolved optical reflectivity

Haiyun Huang, Xiu Zhang, Junzhi Zhu +7

We employ time-resolved optical reflectivity to investigate the ultrafast dynamics of the charge-transfer gap (CTG) in a parent cuprate compound Ca${}_2$CuO${}_2$Cl${}_2$ (CCOC). We obse…
