Joule-assisted silicidation for short-channel silicon nanowire devices

open access: yes, 2011
We report on a technique enabling electrical control of the contact silicidation process in silicon nanowire devices. Undoped silicon nanowires were contacted by pairs of nickel electrodes and each contact was selectively silicided by means of the Joule ...

Electrical Contacts on Silicon Nanowires Produced by Metal-Assisted Etching: a Comparative Approach

open access: yesNanoscale Research Letters, 2016
Silicon nanowires fabricated by metal-assisted chemical etching can present low porosity and a rough surface depending on the doping level of the original silicon wafer. In this case, wiring of silicon nanowires may represent a challenging task.

Thin Film Polycrystalline Silicon Nanowire Biosensors [PDF]

open access: yesNano Letters, 2012
Polysilicon nanowire biosensors have been fabricated using a top-down process and were used to determine the binding constant of two inflammatory biomarkers. A very low cost nanofabrication process was developed, based on simple and mature photolithography, thin film technology, and plasma etching, enabling an easy route to mass manufacture.

Fabrication of Silicon Nanowires and Transistors with Silicon Nanowire-Channels

open access: yesJournal of the Vacuum Society of Japan, 2009
Si nanowires (SiNWs) were synthesized by gold (Au)-catalyzed chemical vapor deposition (CVD). To control the morphology of SiNWs, the growth parameters were systematically changed and they were studied by transmission and scanning electron microscopes and Raman spectroscopy.
