Excited state spectroscopy in carbon nanotube double quantum dots
Sami Sapmaz, Carola Meyer, Piotr Beliczynski +2
We report on low temperature measurements in a fully tunable carbon nanotube double quantum dot. A new fabrication technique has been used for the top-gates in order to avoid cover…
Tunneling in suspended carbon nanotubes assisted by longitudinal phonons
S. Sapmaz, P. Jarillo-Herrero, Ya. M. Blanter +2
Current-voltage characteristics of suspended single-wall carbon nanotube quantum dots show a series of steps equally spaced in voltage. The energy scale of this harmonic, low-energ…
Electronic excitation spectrum of metallic carbon nanotubes
S. Sapmaz, P. Jarillo-Herrero, J. Kong +3
We have studied the discrete electronic spectrum of closed metallic nanotube quantum dots. At low temperatures, the stability diagrams show a very regular four-fold pattern that al…
Electron-hole symmetry in a semiconducting carbon nanotube quantum dot
Pablo Jarillo-Herrero, Sami Sapmaz, Cees Dekker +2
Optical and electronic phenomena in solids arise from the behaviour of electrons and holes (unoccupied states in a filled electron sea). Electron-hole symmetry can often be invoked…
Carbon Nanotubes as Nanoelectromechanical Systems
S. Sapmaz, Ya. M. Blanter, L. Gurevich +1
We theoretically study the interplay between electrical and mechanical properties of suspended, doubly clamped carbon nanotubes in which charging effects dominate. In this geometry…
