Realization of metal-insulator transition and oxidation in silver nanowire percolating networks by terahertz reflection spectroscopy.

Metal-insulator phase transition in a VO2 thin film observed with terahertz spectroscopy

Terahertz spectroscopy studies on epitaxial vanadium dioxide thin films across the metal-insulator transition.

We present results on terahertz (THz) spectroscopy on epitaxial vanadium dioxide (VO(2)) films grown on sapphire across the metal-insulator transition. X-ray diffraction indicates the VO(2) film is highly oriented with the crystallographic relationship: (002)(film)//(0006)(sub) and [010](film)//[2 ̅1 ̅10](sub). THz studies measuring the change in transmission as a function of temperature demonstr...

Effect of oxygen stoichiometry on the insulator-metal phase transition in vanadium oxide thin films studied using optical pump-terahertz probe spectroscopy

Effects of length dispersity and film fabrication on the sheet resistance of copper nanowire transparent conductors.

Development of thin-film transparent conductors (TC) based on percolating networks of metal nanowires has leaped forward in recent years, owing to the improvement of nanowire synthetic methods and modeling efforts by several research groups. While silver nanowires are the first commercially viable iteration of this technology, systems based on copper nanowires are not far behind. Here we presen...

Reversible Metal-Insulator Transition in Ordered Metal Nanocrystal Monolayers Observed by Impedance Spectroscopy

Low frequency impedance spectroscopy was applied on a Langmuir monolayer of alkylthiol passivated 35 Å diameter silver quantum dots, as a function of interparticle separation distance. As interparticle spacing decreases below 30% of particle diameter, a reduction in interparticle charge tunneling time is observed. On further compression, the complex impedance of the films undergoes a transition...
