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(0.3)MoO(3) have been successfully grown on SrTiO(3)(100), SrTiO(3)(110), and SrTiO(3)(510) substrates via pulsed laser deposition. Scanning electron microscopy revealed quasi-one dimensional rod-shaped structures parallel to...

Sumario:High quality epitaxial thin films of the quasi-one dimensional conductor K(0.3)MoO(3) have been successfully grown on SrTiO(3)(100), SrTiO(3)(110), and SrTiO(3)(510) substrates via 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(0.3)MoO(3) thin films demonstrates a metal-to-semiconductor transition at about 180 K. Highly anisotropic resistivity was also observed for films grown on SrTiO(3)(510).
