A unique opportunity for industrial scale fabrication of semiconductor nanowire-based devices

Nikoobkht B., National Institute of Standards and Technology, US

A method is developed which enables horizontal growth of semiconductor nanowires on predefined locations. In this architecture, despite most bottom-up approaches, there is no need for post-growth treatments and alignment of nanowires on a given [...]

Electrical Contacts to Nanotubes and Nanowires: Why Size Matters

Leonard F., Talin A.A., Sandia National Laboratories, US

Electrical contacts play a key role in electronics. As new materials such as nanotubes and nanowires are explored for nanoelectronics, the fundamental aspects of electrical contacts need to be re-examined due to the unique properties [...]

A Circuit-Compatible Model for Ballistic Silicon Nanowire Transistors

Chen J., Agere Systems, US

Silicon nanowire transistors (SNWT) are being extensively explored as a successor to CMOS. Silicon nanowires with a diameter as small as 2nm and having high carrier mobility have been achieved. Such developments shed light on [...]

Nanowire formation for Single Electron Transistor using SEM Based Electron Beam Lithography (EBL) Technique: Positive Tone Vs Negative Tone E-beam Resist

Nuzaihan M., Hashim U., Halim N.H.A., Bajuri S.N.M., Northern Malaysia University College of Engineering, MY
