Mr. Robert Bauer BSc, MSc
PhD Candidate Department of Physics and Engineering PhysicsI am Robert Bauer, a Ph.D. candidate in the Physics and Engineering Department at the University of Saskatchewan, co-supervised by Gap Soo Chang and John Tse. My work focuses on developing bio-organic semiconducting materials derived from flax and investigating the nucleation of ices and gas hydrates under extreme conditions. My research involves the use of spectroscopy and devices to investigate changes in structure and how those changes in atomic structures influence the outward properties of materials. In my work, I look to add value to products such as flax by investigating possible semiconducting properties of molecules extracted from the oil. Using different combinations of 20 amino acids one can form a variety of differing bio-organic molecules that could be used as a semiconductor. I work on using computational methods to help identify promising candidates and experimental methods to test the properties of the materials. We also develop strategies to modify materials to induce additional properties, such as light sensitivity and emission. If Plants can be modified to produce a programmed semiconductor given an appropriate amino acid chain can be sequenced, then it could be the future bio-compatible semiconductors.
