CDW on the Surface & Bulk of Bi2Sr2-xLaxCuO6+d
We combined resonant x-ray scattering (REXS), scanning tunneling microscopy (STM), and angle-resolved photoemission spectroscopy (ARPES) to
observe a charge order that appears consistently in surface and bulk, and in momentum and real space within one cuprate family,
Bi2Sr2-xLaxCuO6+d. Combined with earlier observations of electronic order in other cuprate families, these findings suggest the
existence of a generic charge-ordered state in underdoped cuprates and uncover its intimate connection to the pseudogap regime.
