Research Summary:

Professor Heiman’s research group focuses on several challenging and technologically important areas: (1) topological insulators; (2) nanomagnetism; and (3) novel spintronic materials. The group’s primary experimental tools are: molecular beam epitaxy (MBE) crystal growth; SQUID magnetrometry; electrical and optical measurements in high magnetic fields and at low temperatures. Research is in collaboration with MIT and Leeds University (UK), and is supported by the NSF, DOE and ONR.
