Ultra-Low Noise Multiwalled Carbon Nanotube Transistors
Olli Herranen, Deep Talukdar, Markus Ahlskog
We report an experimental noise study of intermediate sized quasi ballistic semiconducting multiwalled carbon nanotube (IS-MWCNT) devices. The noise is two orders of magnitude lowe…
Strain sensing with sub-micron sized Al-AlOx-Al tunnel junctions
P. J. Koppinen, J. T. Lievonen, M. Ahlskog +1
We demonstrate a local strain sensing method for nanostructures based on metallic Al tunnel junctions with AlOx barriers. The junctions were fabricated on top of a thin silicon nit…
Multiwalled Carbon Nanotubes as Building Blocks in Nanoelectronics
Markus Ahlskog, Pertti Hakonen, Mikko Paalanen +2
Molecular level components, like carbon multiwalled nanotubes (MWNT), show great potential for future nanoelectronics. At low frequencies, only the outermost carbon layer determine…
Multiwalled carbon nanotube: Luttinger liquid or not?
R. Tarkiainen, M. Ahlskog, J. Penttilä +4
We have measured IV-curves of multiwalled carbon nanotubes using end contacts. At low voltages, the tunneling conductance obeys non-Ohmic power law, which is predicted both by the…
Localized and Delocalized Charge Transport in Single-Wall Carbon-Nanotube Mats
O. Hilt, H. B. Brom, M. Ahlskog
We measured the complex dielectric constant in mats of single-wall carbon-nanotubes between 2.7 K and 300 K up to 0.5 THz. The data are well understood in a Drude approach with a n…
