High-sensitive Label-free Biosensors Based on Carbon Nanotube Field-effect Transistors Modified with Aptamers

Maehashi K., Katsura T., Matsumoto K., Kerman K., Takamura Y., Tamiya E., Osaka University, JP

We have fabricated label-free protein biosensors based on aptamer-modified carbon nanotube field-effect transistors (CNTFET) for detection of immunoglobulin E (IgE). Since aptamers are artificial oligonucleotides, the aptamers are smaller in size than the Debye length. [...]

Vertically Grown Coaxial Double Gate Carbon Nanotube Field Effect Transistors for Tera Level Integration

Pourfath M., Gehring A., Cheong B.H., Park W.J., Kosina H., Selberherr S., Vienna University of Technology, AT

Vertically grown carbon nanotubes have the potential for tera-level Integration. However, the well-known ambipolar behavior limits the performance of carbon nanotube field effect transistors. In this work we demonstrate that a double gate structure effectively [...]
