The advance of graphene-based nanoelectronics has been hampered due to the difficulty in producing single- or few-layer graphene over large areas. We report a simple, scalable, and cost-efficient method to prepare graphene using methane-based CVD on nickel films deposited over complete Si/SiO2 wafers. By using highly diluted methane, single- and few-layer graphene were obtained, as conf... View full abstract»

Teflon AF thin films have been directly patterned by electron-beam lithography without the need for chemical development. The pattern depth was found to be linearly related to exposure dose and increases with increasing film thickness. Features as small as 200 nm have been resolved. Fourier transform infrared measurements indicate that the electron-beam-induced patterning is related to degradation... View full abstract»

Magnetite nanoparticles were surface modified with five kinds of agents and used to enhance gene transfection. Standard polyethyleneimine (PEI) transfections were found to be enhanced only for the magnetic nanoparticles with strong surface potentials, since these can form complexes with PEI or genes via electrostatic interactions. Thus, it is not necessary to prepare gene-vector-coated magnetic na... View full abstract»

Using density functional theory calculations, we investigate the electronic structures and field emission properties of carbon nanocones (CNCs). We find that the cohesive and formation energies for various types of CNCs are dependent on the cone angles, while the work function, local density of states, redistribution of the charge, and field emission pattern are sensitive to the morphologies of CN...

Closely packed carbon nanotube (CNT) bundles are expected to have higher conductivity than copper and could potentially replace copper for electrical and thermal conductors in IC chips. However, it is extremely difficult, if not impossible, to controllably grow closely packed CNT bundles. We report on a novel postgrowth capillary densification method, which results in dramatic increase of CNT site... View full abstract»

We report the formation and optical characteristics of GaSb/GaAs type-II quantum dots (QDs) by using an interfacial misfit (IMF) growth mode. A V/III ratio during the growth of GaSb QDs determines the selectivity of IMF and conventional Stranski-Krastanov (SK) growth modes. This transition between SK and optimized IMF QDs is rather abrupt and occurs within a factor-of-2 variations in V/III ratio. ... View full abstract»
