Compositional analysis and optical properties of Co doped TiO2 thin films fabricated by spray pyrolysis method for Dielectric and Photocatalytic applications

Henry Barasa Wafula; Robinson Juma Musembi; Albert Owino Juma; Patrick Tonui; Justus Simiyu; Thomas Sakwa; Deo Prakash; K.D. Verma (2016)

Abstract Cobalt doped TiO2 thin films (CTF) deposited by spray pyrolysis has been studied. The compositional analysis has been done using RBS method, while optical spectroscopy has been done by measuring the transmittance ...
A Surface Photovoltage Study of Surface Defects on Co-Doped TiO2 Thin Films Deposited by Spray Pyrolysis

Henry Wafula; Albert Juma; Thomas Sakwa; Robinson Musembi; Justus Simiyu (2018)

Abstract: Surface photovoltage (SPV) spectroscopy is a powerful tool for studying electronic defects on semiconductor surfaces, at interfaces, and in bulk for a wide range of materials. Undoped and Cobalt-doped TiO2 (CTO) ...
