Michael Steger, a PhD student in Mike Thewalt’s Semiconductor Spectroscopy Lab in SFU’s Department of Physics, has had a great year using optical spectroscopy to study the fundamental properties of semiconductors.
His research into highly isotopically enriched silicon, which enables optical spectroscopy at much higher resolution than natural silicon, led him to become first author on an invited paper presented at the International Conference on the Physics of Semiconductors in Seoul. This paper describes a novel method for studying nuclear spins in silicon, which might lead to a new approach for a silicon-based quantum computer.
Michael has also just wrapped up an invited review for the Journal of Applied Physics, which will form the core of his PhD thesis. This work describes a new technique of ‘isotopic fingerprints,’ which has led to a surprising reevaluation of what were thought to be very well known luminescent defect centers in silicon.
