Surface-enhanced charge-density-wave instability in underdoped Bi2201

Rosen, J. A., Comin, R., Levy, G. et al.

Understand

Neutron and x-ray scattering experiments have provided mounting evidence for spin and charge ordering phenomena in underdoped cuprates.

  • These range from early work on stripe correlations in Nd-LSCO to the latest discovery of charge-density-waves in YBCO.
  • Both phenomena are characterized by a pronounced dependence on doping, temperature, and an externally applied magnetic field.
  • Here we show that these electron-lattice instabilities exhibit also a previously unrecognized bulk-surface dichotomy.
