Tackling the mysteries of nanostructures

"We're setting up a new lab to study quantum effects in nanostructures," says Ganapathy, who joined the Department of Physics, College of Arts and Sciences, as an assistant professor this past fall. "Our main experiments will be studying electron transport in nanostructures at very low temperatures and at high magnetic understand how electrons go from one place to another in one-dimensional and zero-dimensional materials."

There is no lack of knowledge about the behavior of electrons in three-dimensional objects, such as the familiar copper wires through which electrons travel with little resistance; but Ganapathy says scientists possess scant information about the behavior of electrons in lower-dimensional objects. These include one-dimensional objects, such as carbon nanotubes, and zero-dimensional objects, such as quantum dots.
