Surface texture modification of spin-coated SiO2 xerogel thin films by TMCS silylation

Optical properties of spin-coated Er-doped Ga1As39S60 Chalcogenide thin films

Spin-coating of Chalcogenide glasses is a cost-effective and flexible method to produce thin films applicable in photonics. In this paper Er was doped into Ga1As39S60 glass by melt quenching technique and solutions for spin coating were prepared from glass powders dissolved in Propylamine and Ethylendiamine. Substrates used were microscopic slides (refractive index of about 1.51). Applied layer...

Helimagnetic thin films: surface reconstruction, surface spin-waves and magnetization

Fabrication of MgF2-SiO2 Nanocomposite Thin Films and Investigation of Their Optical and Hydrophobic Properties

In this research, MgF2-2%SiO2/MgF2 thin films were applied on a glass substrate. At first, MgF2 thin films with the optical thickness were deposited on the glass slide substrates. Then, MgF2-2%SiO2 thin films were deposited on the glass coated with MgF2 thin films. Finally, the nanocomposite thin films were surface treated by the PFTS solution. Characterization of the thin film was done by X-Ra...

Sol – Gel Spin Coated Cadmium Sulphide ‎Thin Films on Silicon (1 0 0) Substrates for ‎Optoelectronic Applications

Cadmium chalcogenides with appropriate band gap energy have been attracting a great deal of attention because of their potential applications in optoelectronic devices. In this work CdS thin films were deposited on p – type silicon substrates by sol – gel spin coating method at different substrate temperatures. The CdS deposited wafers were characterized by X‐ray diffracti...

Modification of aluminum thin films

We have utilized several processing techniques to locally modify the superconducting transition temperature and the normal state resistivity of aluminum thin films. The techniques of ion implantation, application of a magnetic overlayer, and reactive ion etching have been used to fabricate S-N interfaces with controlled differences in transition temperatures and normal state resistances. Lithog...
