Optimizing Growth of Single-Crystalline Li0.9Mo6O17
ORAL
Abstract
Lithium Purple Bronze (Li0.9Mo6O17, aka LPB) is a quasi-one-dimensional transition-metal oxide that undergoes a superconducting transition at ~1.8 K [1]. We have grown single crystals of LPB via the temperature-gradient-flux technique described by McCarroll and Greenblatt [2], refining the technique to pinpoint the ideal conditions for growth. Crystals were screened for superconductivity through four-probe resistivity measurements. The effect of post-annealing in the presence or absence of oxygen on the physical properties will be presented.
