Self-Aligned Ballistic Molecular Transistors and Electrically Parallel Nanotube Arrays

Self-Aligned Ballistic Molecular Transistors and Electrically Parallel Nanotube Arrays

Carbon nanotube field-effect transistors with structures and properties near the scaling limit with short (down to 50 nm) channels, self-aligned geometries, palladium electrodes with low contact resistance, and high-K dielectric gate insulators are realized. Electrical transport in these miniature transistors is nearly ballistic up to high biases at both room and low temperatures. Atomic-layer-...

Fully transparent thin-film transistors based on aligned carbon nanotube arrays and indium tin oxide electrodes.

Adv. Mater. 2008, 20, 1–5 2008 WILEY-VCH Verlag Gmb The development of mechanically flexible and/or optically transparent electronics could enable next-generation electronics technologies, which would be easy-to-read, light-weight, unbreakable, transparent, and flexible. Potential applications could include transparent monitors, heads-up displays, and conformable products. Recent reports have d...

Super-long aligned TiO2/carbon nanotube arrays.

5 mm long aligned titanium oxide/carbon nanotube (TiO(2)/CNT) coaxial nanowire arrays have been prepared by electrochemically coating the constituent CNTs with a uniform layer of highly crystalline anatase TiO(2) nanoparticles. While the presence of the TiO(2) coating was confirmed by scanning electron microscopy, transmission electron microscopy, Raman spectroscopy and x-ray diffraction, the r...

Performance Projections for Ballistic Carbon Nanotube Field-Effect Transistors

The performance limits of carbon nanotube field-effect transistors ~CNTFETs! are examined theoretically by extending a one-dimensional treatment used for silicon metal–oxide– semiconductor field-effect transistors ~MOSFETs!. Compared to ballistic MOSFETs, ballistic CNTFETs show similar I – V characteristics but the channel conductance is quantized. For low-voltage, digital applications, the CNT...
