Carbon nanotubes (CNTs) are a promising material for high-performance electronics beyond silicon. But unlike silicon, the nature of the transport band gap in CNTs is not fully understood. The transport gap in CNTs is predicted to be strongly driven by electron-electron (e-e) interactions and correlations, even at room temperature. Here, we use dielectric liquids to screen e-e interactions in individual suspended ultra-clean CNTs. Using multiple techniques, the transport gap is measured as… 
Universal interaction-driven gap in metallic carbon nanotubes
Suspended metallic carbon nanotubes (m-CNTs) exhibit a remarkably large transport gap that can exceed 100 meV. Both experiment and theory suggest that strong electron-electron interactions play a
Single-particle states spectroscopy in individual carbon nanotubes with an aid of tunneling contacts
Recent studies have demonstrated that the band structure of a carbon nanotube (CNT) depends not only on its geometry but also on various factors such as atmosphere chemical composition and dielectric
Exciton Peierls mechanism and universal many-body gaps in carbon nanotubes
"Metallic" carbon nanotubes exhibit quasiparticle gaps when isolated from a screening environment. The gap-opening mechanism is expected to be of electronic origin, but the precise nature is debated.
Carbon nanotubes as excitonic insulators
It is predicted numerically that zero-gap armchair carbon nanotubes could be exciton insulators and called into question the Luttinger liquid paradigm for nanot tubes and tests to experimentally discriminate between excitonic and Mott insulators are provided.
Interaction-Driven Giant Orbital Magnetic Moments in Carbon Nanotubes.
This work addresses the outstanding anomaly of exceptionally large orbital magnetic moments in carbon nanotube quantum dots and carries out quasiparticle calculations, and finds the giant magnetic moments can only be captured by considering a self-energy correction to the electronic band structure due to electron-electron interactions.
Momentum-resolved dielectric response of free-standing mono-, bi- and tri- layer black phosphorus.
A comparison of results with electronic structure calculations indicates that the variation of the quasi-particle gap is larger than that of the exciton binding energy, which highlights a deviation from parabolic to linear dispersion and strong anisotropic fingerprints.

PN junctions in nanoscale materials are of interest for a range of technologies including photodetectors, solar cells, and light-emitting diodes. However, Schottky barriers at the interface between

Abstract We report an experimental study of the band structure of individual carbon nanotubes (SCNTs) based on investigation of the tunneling density of states, i.e. tunneling spectroscopy. A common


Many-body effects in electronic bandgaps of carbon nanotubes measured by scanning tunnelling spectroscopy.
Results provide a deeper knowledge of many-body interactions in these 1D systems and a better understanding of their electronic properties, which is a prerequisite for any application of nanotubes in the ultimate device miniaturization for molecular electronics, or spintronics.
The influence of substrate in determining the band gap of metallic carbon nanotubes.
The decreased band gap is attributed to localized doping caused by trapped charges in the substrate that result in inhomogeneous broadening of the Fermi energy, which in turn limits the ability to modulate the conductance.
Substrate-induced Band Gap Renormalization in Semiconducting Carbon Nanotubes
The quasiparticle band gaps of semiconducting carbon nanotubes supported on a weakly-interacting hexagonal boron nitride (h-BN) substrate are computed using density functional theory and the GW Approximation to find that the direct band gaps are renormalized to smaller values in the presence of the dielectric h-BN substrate.

It is shown that self-energy and excitonic effects in single wall carbon nanotubes can be understood in a theory of large radius tubes derived from the theory of two dimensional graphene where the Coulomb interaction leads to a logarithmic correction to the electronic self- energy and marginal Fermi liquid behavior.
