AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
In this thesis we study the interplay between electronic correlations and geometry in single-walled carbon nanotubes by microscopic model calculations. Electronic correlations are expected to be strong because of the low dimensionality of carbon nanotubes. ...
Single-walled carbon nanotubes are highly interesting quasi one-dimensional nanostructures. They possess a multitude of fascinating optical, mechanical and electrical properties, which can be even further expanded through appropriate functionalization stra ...
In this thesis, the electronic structures of low-dimensional carbon allotropes have been studied. In particular, the spatially-resolved photocurrent responses of devices comprising carbon nanostructures were investigated through scanning photocurrent micro ...
Carbon nanotubes the long, cylindrical carbon molecules are the most exciting material discovered lately. They offer the possibility for a large number of applications. My task was to explore the way how we can use multi-walled carbon nanotubes (MWNT) in s ...
Covalent functionalizations represent a very promising avenue to engineer or manipulate carbon nanotubes. However, in metallic tubes the electrical conductance can drop by several orders of magnitude following functionalization, due to sp(3) rehybridizatio ...
A technique to deterministically manipulate individual Carbon Nanotubes (CNT) has been the brick-wall for the boom of CNT based devices. Here we demonstrate dielectrophoresis as an efficient technique to trap individual Single Walled Carbon Nanotubes (SWCN ...
This thesis describes the synthesis of carbon nanotubes (CNTs) by chemical vapor deposition (CVD) and the evaluation of them as tips of atomic force microscope (AFM) probes. Both arc-discharge and CVD grown nanotubes were investigated as AFM tips. Two meth ...
This thesis reports on the investigations performed on electrochemical functionalization and photoelectronic transport properties of individual single-wall carbon nanotubes (SWCNTs). The first part of the thesis is concerned with the controlled modificatio ...
This review presents an overview of the recent progress made in the field of carbon nanotube (CNT)-based field-effect transistors (FETs). Starting from the simplest device architectures, various methods reported for fabricating CNT-FETs are presented. The ...
We characterize the response of isolated single-wall (SWNT) and multiwall (MWNT) carbon nanotubes and nanotube bundles to static electric fields using first-principles calculations and density-functional theory. The longitudinal polarizability of SWNTs sca ...
