Titania nanotube arrays fabricated by means of electrochemical anodization
is currently the main interest of several research groups due to its promising applications. The high aspect ratio, durability, cheap and scalable fabrication technique make it highly attractive material for efficient solar cell. In this regard extensive research work is being carried out to investigate its properties. In this work we were able to find a mechanism for separating a single titania nanotube from the titania nanotube arrays and to measure its electric transport properties using e-beam lithography technique, also we investigated the effect of thermal annealing on the transport properties, we studied the effect of different annealing temperatures on electric properties. As a result of our work we were able to study for the first time electric transport properties on a single level for Titania nanotubes for more efficient solar cell fabrication.
