Indium doped titanium dioxide: A high mobility and low K- nanostructured semiconductor

Compositional analysis done on the synthesized undoped and indium doped titanium dioxide nanoparticles by XRD, EDAX, UV-vis spectroscopy, SEM, parallel plate method. The UV spectograph reveals that the energy band gap is reduced and the wavelength spectrum is shifted towards red from blue region with respect to TiO₂.The electrical properties indicate that the conductivity is around 10-5 mho/cm and mobility is significantly higher than that of un doped TiO₂ and K Value is low. The SEM result reveals that the particles are spherical in nature and coagulated. The decreased energy band gap makes it suitable for semiconducting purpose and is found suitable for application in optoelectronics devices like solar cell, phototransistors etc.
