Spectroscopic ellipsometry study on e-beam deposited titanium dioxide films

Optical properties of TiO2 nanoceramic films as a function of N–Al co-doping

“…Structural changes may occur during the heating process [11]. Such structural changes lead to complications for optical characterization and the quality control of TiO 2 films [12][13][14][15][16].…”

Fabrication and bioactivity evaluation of porous anodised TiO2 films in vitro

“…However, as additional rutile formed during the crystallographic transformation, the dissolution resistance continued to increase, which led to similar pore sizes and porosities of the samples treated at 180 V and 200 V. Figure 4 shows that the control sample exhibited presented the poorest adsorbing ability for proteins and that the protein adsorption ability increased as the applied voltage was increased from 150 V to 180 V. As the applied voltages increase, the thickness, surface roughness and porosity of the anodised TiO 2 layer increase (27), which, in turn, increase the biocompatibility and improve the protein adsorption ability (26). In addition, compared with rutile and amorphous titanium, anatase exhibits better bioactivity (30,31). Therefore, due to the decrease in the amount of anatase on the surface anodised at 200 V, the protein adsorption ability did not obviously change between Group 180 V and Group 200 V.…”

Biaxial stresses, surface roughness and microstructure in evaporated TiO2 films with different deposition geometries

“…They can be prepared by a variety of coating techniques. It has been shown in several studies that the mechanical properties of TiO 2 films depend not only on the preparation techniques but also on the deposition conditions [3][4][5][6][7][8]. In addition, a problem that frequently arises in vacuum coater operation is how to achieve the desired film uniformity over the substrates.…”
