A method for the spatially selective biofunctionalization of silicon micro- and nanostructures is reported, and results are presented for both single-crystal silicon (111) or (100) surfaces. An electroactive monolayer of hydroquinone was formed on th

A fundamental goal of molecular electronics is to design useful transport signatures into solid-state devices through control over the molecular components. In principle, theory and experiment should unite to provide a “chemical intuition” that g

Experimental and computational studies demonstrating that the conduction of compressed, two-dimensional arrays of hexagonally ordered Ag quantum dots (QDs) may be varied through the influence of applied electric fields are reported and discussed. Mon

Cobalt nanoparticles are incorporated into hexagonal honeycomb mesoporous silica to study the effect of nanoscale confinement on magnetic coupling. The superparamagnetic Co particles can fill a significant fraction of the total pore volume and can co

The temperature dependence of the coherent DC conductivity of an Ag quantum dot (QD) monolayer has been computed allowing for size fluctuations of the QDs as well as for packing disorder. The compu...

A solid state, electronically addressable, bistable [2]catenane-based molecular switching device was fabricated from a single monolayer of the [2]catenane, anchored with phospholipid counterions, and sandwiched between an n-type polycrystalline silic

We present the results of ultrafast optical experiments on silver quantum dot super-lattices. Dramatic changes in the electron dynamics occur as a function of interparticle spacing due to enhanced dipolar coupling and, most importantly, electron delo
