Dr. Fuhrer studies the electronic and electromechanical properties of novel nanometer-scale devices. The focus of this research is on devices constructed from components that are naturally structured on the nanometer scale. These "self-assembled" components may be carbon nanotubes, single atomic-layer sheets of layered compounds, or crystalline nanowires. The goal of Dr. Fuhrer's research is to construct novel devices form these nanosturctured elements, in which new behavior can be observed due to the confinement of electrons or lattice vibrations in the nanometer-scale structure. For example, carbon nanotubes, nanometer-diameter wires of pure carbon, confine electrons to travel strictly in one-dimension. This results in a number of new properties, including quantized conductance, greatly reduced scattering, and exotic effects such as the separation of spin and charge excitations. Understanding the behavior of electrons in these one-dimensional conductors may lead to new high-performance transistors, memory cells, interconnect wires, and chemical sensors. Dr. Fuhrer's research spans from the synthesis of these self-assembled materials, through device fabrication, characterization, and electrical measurements both at room and low temperatures. A significant component of Dr. Fuhrer's research is the use of novel scanned-probe techniques to obtain electrical information about nanoscale devices. For example, atomic force microscopy has been used to measure local voltages in current-carrying carbon nanotubes, and to study the effects of local gating on nanotube transistors. Dr. Fuhrer's research has included the first study of the electronic properties of crossed-nanotube heterojunctions, and the first demonstration of a single-electron memory using a carbon nanotube transistor.
