th-cmuir.6653943832-626132018-11-29T07:57:02Z Inducing crystallinity of metal thin films with weak magnetic fields without thermal annealing Stefan S. Ručman Winita Punyodom Jaroon Jakmunee Pisith Singjai Chemical Engineering Chemistry Materials Science Physics and Astronomy © 2018 by the authors. Licensee MDPI, Basel, Switzerland. Since the discovery of thin films, it has been known that higher crystallinity demands higher temperatures, making the process inadequate for energy-efficient and environmentally friendly methods of thin film fabrication. We resolved this problem by sparking metal wires in a 0.4 Tesla magnetic field at ambient conditions under ultra-pure nitrogen flow to replace the annealing of thin films, and thus designed an environmentally friendly and energy-efficient thin film fabrication method. We employed grazing incidence X-Ray Diffraction spectroscopy to characterize crystallinity of Iron, Nickel, Copper and Tungsten thin films prepared by a sparking discharge process in the presence of 0.4 T magnetic field at an ambient temperature of 25◦C. Control experiment was conducted by sparking without a magnetic field present and using ultra-pure nitrogen flow and ambient air containing oxygen. The Iron thin film prepared in ultra-pure nitrogen flow preserved crystallinity even after one year of ageing. Nickel exhibited higher crystallinity when sparked in nitrogen gas flow than when sparked in atmospheric air and was the only element to crystalize under atmospheric air. Tungsten successfully crystalized after just 40 min of sparking and aluminium failed to crystalize at all, even after 12 h of sparking under nitrogen flow. 2018-11-29T07:35:30Z 2018-11-29T07:35:30Z 2018-09-01 Journal 20734352 2-s2.0-85053690791 10.3390/cryst8090362 https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=85053690791&origin=inward http://cmuir.cmu.ac.th/jspui/handle/6653943832/62613 |
