The unique properties of two dimensional (2D) materials make them promising candidates for chemical and biological sensing applications. However, most 2D nanomaterial sensors suffer very long recovery time due to slow molecular desorption at room temperature. Here, we report a highly sensitive molybdenum ditelluride (MoTe2) gas sensor NO2 NH3 detection with greatly enhanced rate. effects gate bias on performance have been systematically studied. It is found that the kinetics can be...
Abstract We present a chemical vapor deposition method for the synthesizing of single-crystal 1T′-MoTe 2 nanowires and observation one-dimensional weak antilocalization effect in first time. The diameters can be controlled by changing flux H /Ar carrier gas. Spherical-aberration-corrected transmission electron microscopy, selected area diffraction energy dispersive x-ray spectroscopy (EDS) reveal 1T′ phase atomic ratio Te/Mo closing to 2:1. resistivity shows metallic behavior agrees well...
