Parallel arrays of bottom-up grown silicon nanowire Schottky barrier field effect transistors (SB FETs) have been fabricated. The nanoshape metal contacts lower the effective Schottky barrier and lead to higher current densities compared to bulk devices.

We report the development of a highly conductive superhydrophobic nanotube composite, which is directly superimposed with a durable dual hole pattern through imprinting techniques. The dual hole pattern was designed to avoid the use of high slenderness ratio structures resulting in a surface which is robust against physical damage.

A simple method has been used to achieve simultaneous N- intercalation and N-doping at graphene/SiC(0001) surfaces through reactions in atmospheric NH3 at 500 ∼C. The majority of N atoms are intercalated under the topmost carbon layer, while a small fraction of N atoms appear as substitutional dopants in the graphene lattice.

A rigid DNA motif is used as a model for studying directed assembly of one-dimensional nanostructures on lithographically patterned nanodot anchors. Nearly 100% placement yield is achieved by matching the inter-nanodot spacing to the length of the DNA nanostructure. The binding is analyzed in terms of a thermodynamic model which provides insight into the bivalent nature of the binding, a scheme that has general applicability for the controlled assembly of a broad range of functional nanostructures.

A materials processing route for the fabrication of substrate-based Au每Ag nanohuts and nanobowls at site-specific locations is described. The route demonstrates that intricately shaped nanostructures can be engineered using the combined capabilities of heteroepitaxial techniques and galvanic replacement reactions.

ZnO hierarchical aggregates have been successfully synthesized by solvothermal methods by reaction of zinc acetate and potassium hydroxide in methanol. The shapes of the aggregates were found to be determined by ratio of Zn2+ and OH ions in the solution, while the size can be controlled from 2 米m to 100 nm.

Assemblies of newly synthesized substituted pentacenes show distinctive nanorod morphology on Au(111). Nanorod morphology and electronic structure are strongly influenced by substitution. The appropriate choice of the substituents is a key that can be used in device engineering.
