Covenant College's Thin Film Growth and Characterization Lab for Undergraduates
On this page you can keep up with the progress for the Physics Department's lab for undergraduate research. This facility was made possible by a grant from the Division of Materials Research at the National Science Foundation, under the Major Research Instrumentation program. In addition, the Sanderson Fund from Covenant College helped with the purchase of several components of the lab. Covenant College has also made possible the purchase of the 0.7 T magnet, as well as providing support for student workers for 4 summers. The Principal Investigator is Prof. Phillip Broussard.
I gave a presentation on the work Angela did at the SESAPS conference in Mobile, AL. Here is the talk that was given. We could not produce films with clean properties as we wished, and with the sabbatical ending soon, will look forward to doing research in summer of 2016.
Angela has finished her summer project and will be heading back to Basil, Switzerland soon. She will be missed. Here is her paper that she did describing her research. I will be on sabbatical this Fall and hope to continue the attempt to produce cleaner Nb thin films to look at Hc2 parallel to the film.
Angela has been growing and measuring many films. Above you can see her in the Georgia Tech cleanroom as we measured the thickness of the niobium films. We are looking at the effect of different cleaning processes on the film properties now.
Angela Hunziker arrived from Europe and has started her research effort. She will be attempting to optimize the niobium deposition process.
Amy Davis gave a great presentation at the 2014 SESAPS conference in Columbia, SC.
Amy Davis has already grown some great Nb! Tc's above 9K, and good Jc plots. Even more importantly, very consistent properties. Way to go Amy!.
Amy Davis has started on her research project learning about superconductivity. We will be looking at bilayers of Nb/Cr. First step is growing Nb films.
It was a quiet time last year, but this summer Amy Davis will carry out a research project in the Thin Film Lab. We will be posting updates as the summer progresses!
