Dielectric measurements on sol-gel derived titania films

Çapan, Rifat; Ray, Asim Kumar (Springer, 2017)

Alternating current (AC) impedance measurements were performed on 37 nm thick nanostructured sol-gel derived anatase titania films on ultrasonically cleaned (100) p-silicon substrates at temperatures T ranging from 100 K ...
Electrical characterisation of stearic acid/eicosylamine alternate layer Langmuir–Blodgett films incorporating CdS nanoparticles

Çapan, Rifat; Ray, Asim Kumar; Hassan, Aseel (Elsevier Science Sa, 2007)

Electrical properties of stearic acid/eicosylamine alternate layer Langmuir–Blodgett (LB) film structure incorporating cadmium sulphide (CdS) nanoparticles are studied in the temperature range 300–400 K. The room temperature ...
Optical dispersion in spun nanocrystalline titania thin films

Çapan, Rifat; Chaure, Nandu B.; Hassan, Aseel; Ray, Asim Kumar (Iop Publishing Ltd, 2004)

Sol-gel derived titanium dioxide (TiO2) films are prepared on silicon substrates using the method of spin-coating with different speeds from 1000 to 6000 rpm. Spectroscopic ellipsometric measurements provide dispersion of ...
