Investigation of charge order in Ca$_{2-x}$Na$_{x}$CuO$_{2}$Cl$_{2}$ using ARPES

ORAL

Abstract

The electronic structure of doped cuprate superconductors Ca2-xNaxCuO2Cl2 of various doping values (including underdoping, optimal doping and overdoping) is investigated using angle-resolved photoemission spectroscopy (ARPES). We discuss our new data in terms of charge order, by comparing them with the ARPES data and the scanning tunneling spectroscopy data in the literature.
