Bipolar single-wall carbon nanotube field-effect transistor
Bakir Babic, Mahdi Iqbal, Christian Schonenberger
We use a simultaneous flow of ethylene and hydrogen gases to grow single wall carbon nanotubes by chemical vapor deposition. Strong coupling to the gate is inferred from transport…
Shot Noise in Schottky's Vacuum Tube
C. Schönenberger, S. Oberholzer, E. V. Sukhorukov +1
In these notes we discuss the origin of shot noise ('Schroteffekt') of vacuum tubes in detail. It will be shown that shot noise observed in vacuum tubes and first described by W. S…
Doping state of multi-wall carbon nanotubes wires and quantum dots
Christian Schönenberger, Mark Buitelaar, Michael Krüger +3
Employing strong electrostatic gating (liquid-ion gating), the position of the Fermi energy E_F (relative to the charge-neutrality point) was determined in multi-wall carbon nanotu…
Amplitude of Aharonov-Bohm oscillations in mesoscopic metallic rings as a function of the DC bias voltage
C. Terrier, C. Strunk, T. Nussbaumer +2
We report measurements of the amplitude of the Aharonov-Bohm oscillations in a mesoscopic diffusive gold ring as a function of the DC bias voltage V. The amplitude of the h/e oscil…
