Effect of lattice mismatch on film morphology of the quasi-one dimensional conductor K 0.3 MoO 3

High quality epitaxial thin films of the quasi-one dimensional conductor K MoO have been successfully grown on SrTiO (100), SrTiO (110), and SrTiO (510) substrates pulsed laser deposition. Scanning electron microscopy revealed quasi-one dimensional rod-shaped structures parallel to the substrate sur...

Description
Summary:High quality epitaxial thin films of the quasi-one dimensional conductor K MoO have been successfully grown on SrTiO (100), SrTiO (110), and SrTiO (510) substrates pulsed laser deposition. Scanning electron microscopy revealed quasi-one dimensional rod-shaped structures parallel to the substrate surface, and the crystal structure was verified by using X-ray diffraction. The temperature dependence of the resistivity for the K MoO thin films demonstrates a metal-to-semiconductor transition at about 180 K. Highly anisotropic resistivity was also observed for films grown on SrTiO (510).
