Self-organized nanocolumnar structure in superhard TiB2 thin films

TiB2 thin films are well known for their high hardness which makes them useful for wear-resistant applications. Overstoichiometric TiB2 deposited at 300 °C by nonreactive sputtering has been shown to exhibit superhardness sHù40 GPad, while the hardness of their bulk stoichiometric counterparts is ,25 GPa. We show, using high-resolution transmission electron microscopy, that overstoichiometric T...

Preparation and Photocatalytic Property of TiO2 Columnar Nanostructure Films

The rutile TiO2 films with columnar nanostructure were prepared by combining the glancing angle deposition (GLAD) technique in magnetron sputtering system with the subsequent two-step annealing treatment. Experimental results showed that all the TiO2 films kept discrete columnar structures as the Ti films deposited by GLAD and accomplished the phase transition from Ti to rutile TiO2. Such TiO2 ...

Patterned nanostructure in AgCoÕPtÕMgO„001... thin films

The formation of a patterned nanostructure in an AgCo/Pt/MgO~001! thin film is simulated by a technique of combining molecular dynamics and phase-field theory. The dislocation ~strain! network existing in Pt/MgO is used as a template whose pattern is transferred to the AgCo phase in spinodal decomposition, resulting in regular arrays of Co islands that are attracted by the dislocations. The inf...
