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 ... -
Spin-coated films of calix[4]resorcinarenes as sensors for chlorinated solvent vapours
Çapan, Rıfat; Çapan, İnci; Davis, Frank; Ray, Asim Kumar (Springer, 2024)Spun thin films were fabricated using two different calix[4]resorcinarene materials. SPR curves of the calix[4]resorcinarenes along with an uncoated gold layer were determined. Exposure of the calix[4]resorcinarene films ...
