Growth of Topological Insulator Nanostructures

Project Title: Growth of Topological Insulator Nanostructures

Project Description: A topological insulator is a material that behaves as an insulator in its bulk but conducts currents on its surfaces. A simple analogy is a bi-layer system where graphene layers are placed on top of ceramic substrates. However, the performance of a topological insulator system is far beyond that of the graphene because of the unique spin transport. In this project, the student will set up a vacuum tube furnace and grow topological insulator nanostructures through a vapor-solid process. The nanostructure will be used for a variety of nanoelectronic devices, such as high mobility transistors.

Anticipated Student Tasks and Responsibilities: Set up tube furnaces, optimize growth conditions, grow topological insulator nanostructures, and fabrication of nanodevices by e-beam lithography.

Qualifications: The student should have a background on material science and semiconductor physics.
