AbstractWe report on the preparation and characterization of semiconductor devices based on porous nano-crystalline TiO2 films. We present experimental results on photoconduction to elucidate the role of trap states in this material. We then analyse the behavior of a SnO2/TiO2/Pt Schottkydiode and finally present spectral photoresponse data obtained on a hetero-junction between TiO2 films and PbS quantum dots. We find that the porous films hold some promise for electronic applications, in which fast reponse times are not required.
