Gate dependent photo-responses of carbon nanotube field effect phototransistors

H Z Chen, N Xi, K W C Lai, L L Chen, R G Yang and B Song



Gate dependent photoconductivity of carbon nanotube (CNT) field effect phototransistors (FEPs) was systematically investigated in this study. The photo-response comparisons of CNT FEPs with symmetric and asymmetric metal structures connecting to the same CNT revealed that the gate effect contributed to a sensitivity improvement with a lower dark current, a higher photocurrent, and an enhanced photovoltage. A functionalized asymmetric FEP, fabricated by partially doping the CNT utilizing a polyethylene imine (PEI) polymer, verified that FEPs delivered a better performance by using asymmetric structures. A multi-gate FEP, with three pairs of side-gates that can electrostatically dope different sections of a CNT independently, was fabricated to examine the gate structure dependent photo-responses. Experimental measurements showed an unconventional photocurrent improvement that was weakly dependent on the gate location, which was attributed to the unique charge distribution of one-di...

Pt–Pd alloy nanoparticle-decorated carbon nanotubes: a durable and methanol tolerant oxygen reduction electrocatalyst

Sourov Ghosh, Ranjan K Sahu and C Retna Raj



We describe the decoration of multiwalled carbon nanotubes (MCNTs) with Pt–Pd alloy nanoelectrocatalysts of three different compositions and their electrocatalytic performance toward the oxygen reduction reaction (ORR). The decoration of the MCNTs involves polymer-assisted impregnation of metal precursors ##IMG## [http://ej.iop.org/images/0957-4484/23/38/385602/nano431900ieqn22.gif] {${\mathrm{PtCl}}_{6}^{2-}$} and ##IMG## [http://ej.iop.org/images/0957-4484/23/38/385602/nano431900ieqn23.gif] {${\mathrm{PdCl}}_{4}^{2-}$} and the subsequent reduction of the impregnated precursors by a modified polyol route. The composition of the catalyst was controlled by tuning the molar ratio of the precursors during their impregnation. Electron probe microscopic analysis shows that the catalysts have compositions of Pt 46 Pd 54, Pt 64 Pd 36 and Pt 28 Pd 72 . The Pt 46 Pd 54 a...

Electron beam induced deposition of silicon nanostructures from a liquid phase precursor

Yin Liu, Xin Chen, Kyong Wook Noh and Shen J Dillon



This work demonstrates electron beam induced deposition of silicon from a SiCl 4 liquid precursor in a transmission electron microscope and a scanning electron microscope. Silicon nanodots of tunable size are reproducibly grown in controlled geometries. The volume of these features increases linearly with deposition time. The results indicate that secondary electrons generated at the substrate surface serve as the primary source of silicon reduction. However, at high current densities the influence of the primary electrons is observed to retard growth. The results demonstrate a new approach to fabricating silicon nanostructures and provide fundamental insights into the mechanism for liquid phase electron beam induced deposition.

Voltage-driven ring confinement in a graphene sheet: assessing conditions for bound state solutions

Leonardo Villegas-Lelovsky, Carlos Trallero-Giner, Victor Lopez-Richard, Gilmar E Marques, Cesar E P Villegas and Marcos R S Tavares



We have systematically studied the single-particle states in quantum rings produced by a set of concentric circular gates over a graphene sheet placed on a substrate. The resulting potential profiles and the interaction between the graphene layer and the substrate are considered within the Dirac Hamiltonian in the framework of the envelope function approximation. Our simulations allow microscopic mapping of the character of the electron and hole quasi-particle solutions according to the applied voltage. General conditions to control and operate the bound state solutions are described as functions of external and controllable parameters that will determine the optical properties ranging from metallic to semiconductor phases. Contrasting behaviors are obtained when comparing the results for repulsive and attractive voltages as well as for variation of the relative strength of the graphene–substrate coupling parameter.
