Crystal Growth of Quasi-One Dimensional SrNbO$_{3.41}$ and LaTiO$_{3.41}$

POSTER

Abstract

Single crystals of SrNbO$_{3.41}$ and LaTiO$_{3.41}$ were grown in order to investigate the physical properties of these quasi- one dimensional conductors. Single crystals growth was accomplished with an optical image furnace; characterization was performed with X-ray powder diffraction. The resistance and heat capacity of SrNbO$_{3.41}$ were measured in the temperature range 300 K $> T >$ 0.3 K. SrNbO$_{3.41}$ was annealed to examine the influence of oxygen content on the electrical resistivity. The Debye temperature and electronic heat capacity coefficient of SrNbO$_{3.41}$ were found to be 458.5 $\pm$ 0.2 K and 0.77 $\pm$ 0.07 mJ/mol K respectively.
