Novel Phenomena in Dilute Electron Systems in Two Dimensions
(City College of New York)
Abstract: Based on theoretical and experimental work over
the past two decades, all two-dimensional systems of electrons were believed
to be insulating in the limit of zero temperature. Recent experiments
will be reviewed which indicate that dilute, strongly interacting two-dimensional
systems exhibit unexpected behavior that is currently the focus of intense
interest: an apparent transition to a conducting phase, and a dramatic
increase in resistivity in response to an in-plane magnetic field.
