Vanadium dioxide (VO2) as a phase-change material controls the transferred heat during phase transition process between metal and insulator states. At temperature above 68°C, the rutile structure VO2 keeps the heat out and increases the IR radiation reflectivity, while at the lower temperature the monoclinic structure VO2 acts as the transparent material and increase the transmission radiation. In this paper, we first present the metal-insulator phase transition (MIT) of the VO2 in high and low… 

Design, fabrication, and spectral characterization of temperature-dependent liquid crystal-based metamaterial to tune dielectric metasurface resonances

Tunable dielectric meta-surface nanostructures offer incredible performance in optical application due to their extraordinary tunability of the polarization and engineering the dispersion of light

Design, fabrication, and spectral characterization of TM-polarized metamaterials-based narrowband infrared filter

Hyperbolic Metamaterials, as a non-magnetic anisotropic artificial structure, show metal properties in one direction and dielectric behavior in orthogonal directions. The proposed hyperbolic



Properties of VO2 Films Sputter-Deposited from V2O5 Target

Rutile VO2 is a thermochromic material that exhibits a reversible metal-insulator phase transition upon thermal cycling. A new deposition process of rutile VO2 from a V2O5 target was developed using

Tuning phase transition temperature of VO2 thin films by annealing atmosphere

A simple new way to tune the optical phase transition temperature of VO2 films was proposed by only controlling the pressure of oxygen during the annealing process. Vanadium films were deposited on

Physical Analysis of VO2 Films Grown by Atomic Layer Deposition and RF Magnetron Sputtering

Among the many vanadium suboxides and different stoichiometries, VO2 has received considerable attention due to its remarkable metal-insulator transition (MIT) behavior, which causes a significant

Atomic Layer Deposition of Vanadium Dioxide and a Temperature-dependent Optical Model

A model was created to fit to the data for VO2 in its metallic and insulating phases in the near infrared spectral region, and the permittivity and refractive index of the ALD VO2 agreed well with the other fabrication methods in its insulating phase, but showed a difference in its Metallic state.

VO2 films with strong semiconductor to metal phase transition prepared by the precursor oxidation process

We describe a relatively simple, reliable, and reproducible preparation technique, the precursor oxidation process, for making VO2 films with strong semiconductor-to-metal phase transition.

Vanadium Oxide Thin Films Obtained by Thermal Annealing of Layers Deposited by RF Magnetron Sputtering at Room Temperature

This chapter describes a new deposition method proposed to achieve Vanadium Oxide VO x /V 2 O 5 thin films with high temperature coefficient of resistance (TCR), intended to be used as functional

Inverting the thermal radiative contrast of vanadium dioxide by metasurfaces based on localized gap-plasmons

Vanadium dioxide (VO2) is a promising phase-change material (PCM) in controlling radiative heat transfer because of the large permittivity contrast between the phases and the moderate metal-insulator

Growth control of the oxidation state in vanadium oxide thin films

Precise control of the chemical valence or oxidation state of vanadium in vanadium oxide thin films is highly desirable for not only fundamental research but also technological applications that
