Quasiparticle excitations in a one-dimensional interacting topological insulator: Application for dopant-based quantum simulation
David Mikhail, Benoit Voisin, Dominique Didier St Medar +3
We study the effects of electron-electron interactions on the charge excitation spectrum of the spinful Su-Schrieffer-Heeger (SSH) model, a prototype of a 1D bulk obstructed topolo…
Confined Electron and Hole States in Semiconducting Carbon Nanotube sub-10 nm Artificial Quantum Dots
Gilles Buchs, Dario Bercioux, Leonhard Mayrhofer +1
We show that quantum confinement in the valence and conduction bands of semiconducting single-walled carbon nanotubes can be engineered by means of artificial defects. This ability…
Identifying signatures of photothermal current in a double-gated semiconducting nanotube
Gilles Buchs, Salvatore Bagiante, Gary A. Steele
The remarkable electrical and optical properties or single-walled carbon nanotubes (SWNT) allowed for engineering device prototypes showing great potential for applications such as…
Fast and efficient photodetection in nanoscale quantum-dot junctions
Ferry Prins, Michele Buscema, Johannes S. Seldenthuis +8
We report on a photodetector in which colloidal quantum-dots directly bridge nanometer-spaced electrodes. Unlike in conventional quantum-dot thin film photodetectors, charge mobili…
Imaging the formation of a p-n junction in a suspended carbon nanotube with scanning photocurrent microscopy
Gilles Buchs, Maria Barkelid, Salvatore Bagiante +2
We use scanning photocurrent microscopy (SPCM) to investigate individual suspended semiconducting carbon nanotube devices where the potential profile is engineered by means of loca…
