“…Pulsed laser deposition (PLD) technique is used for its uniform and stoichiometry deposition [8][9][10][11][12]. Nd-YAG laser at 355 nm is used to deposit a thin film onto the substrate, and the deposition is carried out in a chamber at oxygen (O 2 ) atmosphere [13][14][15][16][17][18][19][20].…”

V2O5 thin films are analyzed for the substitution of SiO2 to reduce the leakage current in devices when SiO2 becomes ultrathin in submicron technology. Vanadium pentoxide (V2O5) has a high-k dielectric constant of 25 and can be replaced as a gate oxide in the field-effect transistor. V2O5 is deposited using pulsed laser deposition (PLD) in the oxygen (O2) environment at room temperature and characterized. The films surface morphology has been examined by scanning electron microscopy. The capacitance, dielectric constant, and dielectric loss are analyzed for fabricated metal oxide semiconductor (MOS) structure using Solartron SI-1260 impedance analyzer. The transfer characteristic of the fabricated device is analyzed using National Instruments NI-PXI 4110. The ION/IOFF ratio of 106 and threshold voltage (VTH) of 0.6 V is obtained.

Transparency of VO 2 thin films in the visible region is an important aspect of study for its use in smart window applications. In this regard, we experimentally validate the theoretical prediction regarding the influence of scandium (Sc) doping on modulating the optical spectrum of VO 2. Sc-doped nano-crystalline VO 2 , bulk and thin films were synthesised using a two-step process involving a rapid non-equilibrium solution combustion process and ultrasonic nebulised spray pyrolysis of aqueous combustion mixture respectively; followed by a reduction step. The presence of Sc was determined by X-ray photoelectron spectroscopy where a peak observed at 530.06 eV is attributed to Sc-O interaction. Raman spectra showed a shift in 611 cm −1 peak position to a lower wavenumber due to tensile strain arising from Sc doping. Sc-doped VO 2 thin films showed semiconductor to metal transition of four orders of magnitude change in resistance. Sc-doping increased the band gap from 1.76 eV for undoped to 2.02 eV with 2.0 at. % of doping thereby making the films more transparent in the visible region of the optical spectrum. This shift in the band gap of VO 2 was consistent with the theoretical reports. Thus, Sc is a potential dopant for modulating the optical spectrum of VO 2 for its application in smart windows.
