Wafer-Scale Synthesis
of PbTe Nanowires

ACS Nano 3 (2009) 4144. LPNE can be used to blanket a centimeter-scale surface with PbTe nanowires that are stoichiometric, crystalline, and electronically conductive.

Reconnectable Sub-5nm Gaps
in Ultra-Long Gold Nanowires

Nano Letters 9 (2009) 2133. Gold nanowires can be programmed to fail by electromigration yielding a nanometer-scale gap. This break is so small that it can be reconnected by applying a second voltage pulse or voltage scan. Many (>50) gap-formation and reconnection cycles can be carried out on a single nanowire.

Fast, Sensitive Hydrogen Gas Detection
Using Palladium Nanowires that Resist Fracture

Nano Letters 9 (2009) 2177. Our first examination of the hydrogen sensing properties of a single palladium nanowire. It's fast, it's sensitive, but its most surprising feature is that it doesn't break!
