“…1); in the first, (1) vapor phase method [11][12][13], besides Ti layer on substrate, another source such as Ti, TiO, and Ti:C tablet is used while in the second, (2) thermal oxidation method [14][15][16], only Ti layer on substrate is used.…”

“…There are many reports on the synthesis of TiO 2 nanowires [14][15][16][17][18][19][20][21][22][23][24][25][26][27] where have used first or second methods and all of them have common feature, namely presence of Ti layer on substrate before nanostructures growth. These processes are indicated by star symbol in Fig.…”

Identifying the growth factors of nanowires helps in controlling their structure and morphology and determining their optimal growth conditions. This study investigates the effect of titanium substrate in growing TiO 2 nanowires (NWs) with evaporation method. It reveals that the titanium in substrate is indeed the main source of growth. Using the substrate as the only source of growth with regulated amount of accessible oxygen in the furnace, NWs with lengths ranging from 1 to 70 lm were obtained. The results of the experiments show that the nanowires' growth is mainly controlled by diffusion of titanium atoms from the substrate through TiO 2 grain boundaries and surface diffusion toward NWs' tips rather than adsorption from vapor phase. The solid-liquid-solid mechanism including two factors (Ti and O) is proposed and discussed for growth of TiO 2 NWs.
