Nanostructured NdFeB films processed by rapid thermal annealing

Ti/Si thin films during ultra rapid thermal annealing

WC introduce a new technique for rapidly heating (10’ “C/s) thin films using an electrical thermal annealing (ETA) pulse technique. By applying a high-current dc electrical pulse to a conductive substrate-heater material (Si), joule heating occurs thus heating the thin film. This method was demonstrated by heating thin films of aluminum at rates ranging from lo3 to lo6 “C/s. The temperature of ...

High coercivity CoCrPt films achieved by post-deposition rapid thermal annealing

Post-deposition rapid thermal annealing ~RTA! was performed on multilayered films consisting of a Mn capping layer on top of CoCrPt/CrTi/NiAl. High coercivities were achieved even at low M rt values and coercivity values increased more than that would have been predicted by the decrease in magnetization values. This is most likely due to the significant decrease in intergranular exchange coupli...

Ferroelectric and microstructural characteristics of SrBi2Ta2O9 thin films crystallized by the rapid thermal annealing process

Thermal Plasma Deposition of Nanostructured Films

A thermal plasma process for the synthesis of nanoparticles and their immediate assembly into nanostructured films is discussed. In this process, known as hypersonic plasma particle deposition, a thermal plasma with injected precursors is expanded through a nozzle to nucleate nanoparticles, which are then inertially deposited onto a cooled substrate in vacuum. A lightly consolidated nanostructu...

Rapid Synthesis of Nanostructured Pure Anatase TiO2 with High Thermal Stability by Polymeric Sol-Gel Route

The nanostructured anatase TiO2 with high thermal stability was prepared by polymeric sol-gel method without any additives. The particle size distribution of polymeric titania sol was determined by dynamic light scattering (DLS). Then properties of obtained titania were investigated by TG-DTA, XRD, FESEM and TEM. Also, the decolorization capability of resultant anatase was evaluated using methy...
