Welcome to my old web page at GU Physics. This is my old world when I was a PhD Research Student at the Department of Physics and Astronomy (now is School of Physics and Astronomy) of the University of Glasgow. For my detailed profile, please refer to my Wordpress web at http://ducthe.wordpress.com. I only use this web as a world to store my publications.

DUC-THE NGO’s PUBLICATION

Up to now, I have more than 25 publications in peer-reviewed journals, many presentations in conferences and some invited talks (including lectures and tutorials). Most of them are involved in my research of magnetic thin films and materials. Some others concern my collaboration in nanochracterisation and magnetic measurements. My name appeared as D-T. Ngo, or N. D. The.
