Synthesis of VO_2 Nanowire and Observation of the Metal-Insulator Transition
We have fabricated crystalline nanowires of VO_2 using a new synthetic
method. A nanowire synthesized at 650^oC shows the semiconducting behavior and
a nanowire at 670^oC exhibits the first-order metal-insulator transition which
is not the one-dimensional property. The temperature coefficient of resistance
in the semiconducting nanowire is 7.06 %/K at 300 K, which is higher than that
of commercial bolometer.Comment: 3 pages, 4 figures, This was presented in NANOMAT 2006 "International
