The Characterization and Assembly of VO2 Nanostructures

Vanadium dioxide is researched for tuning electrical properties, optical properties and metal-insulator properties. The metal-insulator transition is captivating, for it occurs around room temperature. The transition temperature could be further reduced to even closer to room temperature by doping with molybdenum (Mo). Which is beneficial for several applications, such as thermochromic smart windows. In this project we have successfully synthesized VO2 and Mo doped VO2 by solution process method. The characterization of the product was possible by X-ray diffraction (XRD), energy dispersive X-ray spectroscopy (EDS), transmission electron microscopy (TEM), and differential scanning calorimetry (DSC). Controlling the organization of assembly could help advance the promising properties of VO2 nanostructures.
