Refined crystal growth and characterization of the high-T$_{c}$ superconductor HgBa$_{2}$CuO$_{4+\delta }$

ORAL

Abstract

Among the high-T$_{c}$ superconductors, HgBa$_{2}$CuO$_{4+\delta }$ (Hg1201) is one of the most desirable systems for experimental study due to its relatively simple structure and high T$_{c}$. For quantitative experimental work, it is necessary to grow sizable, high-quality crystals, and to obtain fine oxygen/doping control. Here we report on our most recent improvements in the growth and characterization of Hg1201, leading to further improved sample quality. Our new results include charge transport, magnetic susceptibility, and x-ray photoelectron spectroscopy (XPS) measurements.
