Thin-Film GMI Elements with High Sensitivity.

Thin-film sensing with planar terahertz metamaterials: sensitivity and limitations.

The limiting effects of varying the thickness of a dielectric overlayer on planar double split-ring resonator (SRR) arrays are studied by terahertz time-domain spectroscopy. Uniform dielectric overlayers from 100 nm to 16 mum thick are deposited onto fixed SRR arrays in order to shift the resonance frequency of the electric response. We discuss the bounds of resonance shifting and emphasize the...

Thickness Dependence of Sensitivity in Thin Film Tin Oxide Gas Sensors Deposited by Vapor Pyrolysis

Transparent SnO2 thin films were deposited on porcelain substrates using a chemical vapor deposition technique based on the hydrolysis of SnCl4 at elevated temperatures. A reduced pressure self-contained evaporation chamber was designed for the process where the pyrolysis of SnCl4 at the presence of water vapor was carried out. Resistive gas sensors were fabricated by providing ohmic contacts o...

Theory of Magnetostatic Coupling in Thin-Film Rectangular Magnetic Elements

Towards high efficiency thin film solar cells

As an alternative to single crystal silicon photovoltaics, thin film solar cells have been extensively explored for miniaturized cost-effective photovoltaic systems. Though the fight to gain efficiency has been severely engaged over the years, the battle is not yet over. In this review, we comb the fields to elucidate the strategies towards high efficiency thin films solar cells and provide poi...
