How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
Glass poling and electric field assisted dissolution (EFAD) are techniques that require moderately high temperature and high voltage to be applied to a glass sample in order to drift ions into the glass bulk. Ellipsometry and spectrophotometry are used to determine the change in optical properties of the samples. I also use e-beam vapor deposition and spin-coating to produce thin films, and photolitography to produce structures. Profillometry and optical microscopy are new additions to our lab.

  • I am an experimental physicist and I am working on ion exchange in glass. I use E-beam vapor deposition and spin-coating to produce thin films and photolitography to create microstructures on thin films. Glass poling and electric field assisted dissolution are the processes I perform to drift ions into the glass bulk. Ellipsometry/spectrophotometry are used optically characterize samples. I am also modeling the samples optical properties/thicknesses using data retrieved from ellipsometry.

Metal nanoparticles are used in optical coatings and sensors due to their absorption in optical part of spectrum and its sensitivity to the environment induced by localized surface plasmon resonance. Glass is the most common substrate used for optical coatings. However, its surface does not have optimal properties for coating with metal nanoparticl...
The process of glass poling and electric field assisted dissolution of metal films on coated glass substrates is investigated. The samples consist of soda lime glass substrates coated with thin dielectric layers of different materials (SiO2, Al2O3, TiO2) and an Ag film. The samples are subjected to the application of dc voltage at 200 °C. As a resu...
Glass is important as a substrate for coatings in a wide range of applications or as a substrate for the fabrication of optical micro/nano structures. Coating by wet chemistry methods often demands modifications of the glass surface properties involving several steps. In addition, the micro/nano structuring is usually a several-step process. New me...
The evolution of electric field assisted dissolution (EFAD) of nanoparticles process is studied by means of spectroscopic ellipsometry. Multilayer structures with embedded Ag islands films are prepared by electron beam evaporation and subjected to EFAD process using different voltages and treatment times. Modelling of ellipsometric data evidences t...
Application of electric field and moderately elevated temperature depletes the side facing anode from alkali present in glasses. The change of composition of the treated glass results in variation of refractive index depth profile within the treated glass. Spectroscopic ellipsometry is employed for characterization of optical properties of glass tr...
Conference Paper
Glass poling changes composition of the treated glass depleting the side facing anode from alkali species naturally present in glasses. The resulting change of the treated glass refractive index profiles was studied using ellipsometry.
