Synthesis of Anatase Titania Nanostructures at Room Temperature by PECVD Technique

Keywords： Nanostructures , Plasma enhanced chemical vapor deposition , Anatase titania ,

titania nanostructures have been synthesized at room temperature by plasma enhanced chemical vapor deposition （PECVD） process on silicon （100） substrates using titanium tetraisopropoxide [Ti（OC3H7）4, TTIP] vapor, argon and oxygen mixtures under various deposition pressures. The deposited titania has been characterized for its structural, morphological and chemical composition by X-ray diffraction, scanning electron microscopy, energy dispersive X-ray （EDX） spectroscopy and Fourier transform infrared （FTIR） spectroscopy recordings. With the variation of deposition pressure, titania assumes various nanostructures viz. nanocrystals, nanoparticles, noanorods and comb-like structure. EDX and FTIR measurements show that the deposited titania is of high chemical purity. The possible growth mechanisms for the observed titania nanostructures have been discussed.
