In-situ grown horizontal carbon nanotube membrane

Mihai Adrian Ionescu, Dimitrios Tsamados, Hoël Maxime Guérin

We present the successful fabrication of horizontally grown and dense carbon nanotube (CNT) membranes in situ. A TiN/Al2O3/TiN stack is first patterned to be employed as a support for the CNT growth. Iron is then evaporated with a 45 degrees tilt angle on ...

Streched organic transistors maintain mobility on flexible substrates

Jürgen Brugger, Mihai Adrian Ionescu, Andreea Veronica Savu, Dimitrios Tsamados, Katrin Sidler Arnet, Nenad Cvetkovic

Two levels of aligned stencil lithography were used to fabricate pentacene thin film transistors on 12 mu m thick flexible polyimide substrates. Flexible transistors with 20 x 40 mu m(2) channels were electrically measured under strain up to 2.6%. After on ...

Horizontally and on-site grown carbon nanotube membrane for sensitive and selective gas sensing

Mihai Adrian Ionescu, Dimitrios Tsamados, Hoël Maxime Guérin

We report here the fabrication of a sensitive and selective gas sensor using a carbon nanotube (CNT) membrane as the gas sensing transducer. A TiN/Al2O3/TiN stack is used as a support for the CNT growth catalyst, evaporated with a 45° tilt angle on the ver ...
