Séamus Davis images Nematic Transport in Underdoped HTc Superconductors

Scientists studying high-temperature superconductivity know that the introduction of dopant atoms leads to the development of superconductive behavior. However there is a lack of experimental work showing what these dopants do to the atomic-scale electronic structure of superconductive materials. Professor of physics J.C. Séamus Davis has now imaged the effects of these impurity atoms. His work is published in the February 17 edition of Nature Physics.

Davis’ results show regular pattern of anisotropic scattering of quasiparticles in the substrate that is proportional to the dopant density.
