- Research Statement:
- Professor Bezryadin is currently working on experiments in three critical and related areas of the physics of low-dimensional nanoscale systems: (i) Quantum superconductor-insulator transitions in one-dimensional superconductors; (ii) Electronic properties of DNA molecules; and (iii) Aharonov-Bohm effects in carbon nanotubes. In each case, he has pioneered novel experimental approaches to probe the behavior of the ultrasmall structures. Experiments at the nanoscale can provide new insights into fundamental properties of mesoscopic quantum systems and could be used in the development of highly integrated quantum computers.
Scanning electron microscope micrograph of a 7-nm-thick MoGe nanowireResearch focus: Macroscopic quantum phenomena in low-dimensional superconductors at ultralow temperatures. The SEM micrograph to the left shows a suspended MoGe nanowire (gray). This nanowire is produced by depositing an amorphous MoGe alloy over the surface of a carbon nanotube suspended over a trench (black) in the substrate. The width of the resulting wire is about 7 nm; thus it is probably the thinnest superconductor ever measured. The goal of the project is to understand the nature of the superconductor-insulator transition found in such samples. One of the current theories suggests that the insulating state is caused by macroscopic quantum fluctuations between the normal and superconducting states. Professor Bezryadin's group is one of the leading groups studying one-dimensional superconductivity.
