Accessing the entire overdoped regime in pristine YBa[subscript 2]Cu[subscript 3]O[subscript 6 + x] by application of pressure

We uncover the previously inaccessible overdoped regime to attain the complete superconducting dome in a pristine high temperature cuprate superconductor, by applying pressures up to 280 kbar to single crystals near stoichiometric YBa[subscript 2]Cu[subscript3]O[subscript 7]. The obtained supercondu...

Description
Summary:We uncover the previously inaccessible overdoped regime to attain the complete superconducting dome in a pristine high temperature cuprate superconductor, by applying pressures up to 280 kbar to single crystals near stoichiometric YBa[subscript 2]Cu[subscript3]O[subscript 7]. The obtained superconducting phase boundary as a function of hole doping closely follows the form of the superconducting dome in La[subscript 2−x]Sr[subscript x]CuO[subscript 4]. Measurements are now enabled to trace the evolution of various entangled phases and the Fermi surface from the underdoped to overdoped regime in a single high purity cuprate superconducting family of materials.
