Carbon nanotube field-effect devices with asymmetric electrode configuration by contact geometry
Yotprayoonsak, Peerapong; Talukdar, Deep; Ahlskog, Markus (American Institute of Physics, 2014)We have studied experimentally the conductive properties of single walled carbon nanotube (SWNT) based field-effect type devices, with different contact geometries at the connecting electrode. The device designs are ... -
Individual arc-discharge synthesized multiwalled carbon nanotubes probed with multiple measurement techniques
Ahlskog, Markus; Hokkanen, Matti J.; Levshov, Dmitry; Svensson, Krister; Volodin, Alexander; van Haesendonck, Chris (American Institute of Physics, 2020)Arc-discharge synthesized multiwalled carbon nanotubes (AD-MWNT), or related MWNTs, exhibit a good quality compared to the more common type of MWNT synthesized by catalytic chemical vapor deposition methods. Yet experimental ... -
Carbon nanotube memory devices with high-κ gate dielectrics
Rinkiö, Marcus (University of Jyväskylä, 2009)In this thesis the memory effect and negative differential resistance (NDR) rising from the hysteresis present in carbon nanotube field-effect transistors (CNT-FETs) with high-κ gate dielectrics is discussed. A high-yield ... -
Preparation of Highly Porous Carbonous Electrodes by Selective Laser Sintering
Lahtinen, Elmeri; Kukkonen, Esa Petteri; Jokivartio, Joonas; Parkkonen, Joni; Virkajärvi, Jussi; Kivijärvi, Lauri; Ahlskog, Markus; Haukka, Matti (American Chemical Society, 2019)Selective laser sintering (SLS) 3D printing was utilized to fabricate highly porous carbonous electrodes. The electrodes were prepared by using a mixture of fine graphite powder and either polyamide-12, polystyrene, or ...
