Conductivity of the Crystalline Boron Nanowires Measured in TEM

Lourie O., Gatan Inc., US

In this experiment we report on using in-situ STM-TEM system and EELS to characterize the electronic properties of the boron nanowires. We use low loss EELS approach to study the band structure and the dielectric [...]

Novel Method for the Electrochemical Synthesis of Nickel-Rich Oxide Nanowires

Thorne S.A., Bhargava Y.V., Mintz T.S., Radmilovic V., Suzuki Y., Devine T.M., University of California-Berkeley, US

Using a novel electrochemical process, functionalized and self-assembled Ni-rich oxide nanowires were grown from an Alloy 600 (Ni – 15.5 a/o Cr, 8a/o Fe) substrate. The formation of the nanowires occurs in a high-temperature (238-288 [...]

Conductive Films of Ordered High-Density Nanowire Arrays

Kulkarni J.S., Daly B., Ziegler K.J., Crowley T., Erts D., Polyakov B., Morris M.A., Holmes J.D., University College Cork, IE

We have prepared high-density, ordered arrays of semiconductor nanowires within the pores of mesoporous thin films (MTFs) and anodized aluminum oxide (AAO) matrices using a supercritical fluid solution-phase inclusion technique. Conductive atomic force microscopy (C-AFM) [...]

Fabrication of Silicon Nanowires Using Atomic Layer Deposition

Gopireddy D., Takoudis C.G., Gamota D., Zhang J., Brazis P.W., University of Illinois at Chicago, US

We will present the synthesis of silicon nanowires using Atomic Layer Deposition (ALD) technique. ALD allows the growth of nanowires in a controlled fashion using the nanoparticles as the seed. The diameter and the length [...]

A New Wet Chemical Approach to the Selective Synthesis of Silver Nanowires

Hernandez E.A., Posada B., Irizarry R., Castro M.E., The University of Puerto Rico, US

A new wet chemical approach is presented for the selective synthesis of silver nanowires based on the assembly of silver nanoparticles covered with a bi-functional thiol. The particles are formed spontaneously upon the addition of [...]

Surface Shaping by Ion Beams at Grazing Incidence: Simulations vs. Experiment

Stepanova M., Dew S.K., University of Alberta, CA

Miniaturization of electronic technologies highlights special approaches such as selforganization of nanostructures. Particularly, surface etching by ion beams at grazing incidence is of interest for applications, because it provides pronounced submicron size, self-organized ripples. Formation [...]
