Research Interests

Transport in nanoscale materials, including nanowires and nanotubes, is extremely sensitive to nanoscale structure, including defects, dopants, and impurities.  While methods of resolving spatial structure, such as electron microscopy, are well developed, general methods of resolving nanoscale electronic structure are needed to understand the consequences of dimensionality for the properties of heterogeneous nanostructures.  The Lauhon group combines scanning probes with electrical transport studies of nanowire and nanotube-based devices to correlate nanoscale structure with nanoscale properties, providing a fundamental foundation for the development of new materials technologies of relevance to electronics, photonics, and energy.  We are currently investigating the effects of size, strain, and stoichiometry on the metal-insulator transition in vanadium oxide nanowires, and the influence of dopant inhomogeneities on the electronic properties of silicon and germanium nanowires.
