Professor Bezryadin received his Ph.D. in physics from Joseph Fourier University (France) in 1995. His thesis research was on nanotechnology and superconductivity. Prior to joining the faculty of the Department of Physics at Illinois in the year 2000, Professor Bezryadin held postdoctoral research appointments at the Delft University of Technology (Netherlands) and at Harvard University (1997-2000).
Professor Bezryadin is a remarkable experimentalist who explores physics at the nanoscale. He is developing innovative nanofabrication techniques to enable novel investigations of the properties of superconducting systems with dimensions approaching 5 nm, which is a virtually unexplored size scale at which macroscopic quantum effects have a strong impact on superconducting devices. His research group has fabricated and studied some of the world's tiniest nanowires, DNA-templated superconducting quantum interference , qubits, and memory elements. The current research is focused on superconducting qubits, topological insulators, magnetic molecular devices, and Majorana fermions.
Graduate students are invited to conduct research within the following projects:
(2) Chiral molecular spintronics. Description: The goal of this proposal is to develop a new family of advanced molecular spintronics devices which will lead to quantum sensors, information storage systems, and secure communications. We propose a novel direction of research, termed 'chiral molecular spintronics', in which the next generation molecular-scale, spin-selective and spin-sensitive devices will be developed. The difference with respect to the previous reported spintronics devices is that our new proposed devices will be based on individual single molecules, such as chiral DNA molecules and carbon nanotubes (CNTs). There are published examples where chiral properties of molecules are used to control magnetic systems, but only at the macroscopic level. Here we propose to advance this field to achieve nanoscale devices based on single molecules. The list of advantages of such devices includes their compact nanoscale dimensions, precise structural control, and the ability to self-assemble with high precision. At the conclusion of this project, we will create hybrid systems in which the spin selectivity and the spin torque will be induced through the chirality of the DNA as well as carbon nanotube molecules. Antiferromagnetic nanowires and nanoparticles will be formed by depositing a few atomic monolayers of the desired material over suspended molecules.
