Quantum Electronics

Abstract

When electrons are confined in one or more dimensions, their wave nature and quantum mechanical effects become very apparent. Devices such as quantum wires and quantum dots operate based on this principle. We work on fabricating such devices by exploiting the inherent properties of nanotubes and nanowires.

Project Description

When electrons are confined in one or more dimensions, their wave nature and quantum mechanical effects become very apparent. Devices such as quantum wires and quantum dots operate based on this principle. However, for such effects to be visible at room temperature, the size of the confinement has to be no more than a few nanometers. Such devices are extremely difficult to fabricate using traditional lithography-based fabrication due to the limit in patterning resolution. However, nanowires and nanotubes provide natural choices for making such devices since they already have confinement in two dimensions. Moreover, they allow for new ways of creating extra degrees of confinement. For example, mechanical deformation in nanotubes can lead to significant change in electronic structure, enabling the realization of nanoscale quantum devices, potentially capable of operating at room temperature. In addition to providing a great vehicle for the study of quantum physics, other possible applications of these structures include future electronic technologies, turnstile devices and nanophotonics.
