Propriétés électroniques de tubules et d'échantillons contenant des nanotubules carbonés

Abstract : This work presents theoretical studies about elastic stress affects on electronic properties of carbon nanotubes. A model taking into account the curvature induced by conformal mapping has been estblished in the framework of a tight-binding scheme. This model has been used with usual boundary conditions to compute an analytic expression of the electronic density of states (DOS) by the Green's function method. Our results show that curvature is responsible for a gap opening in the DOS. This modification of the electronic properties of tubules is a kind of Peierls instability. Influence of uniaxial stress on armchair and zigzag nanotubes has been investigated. Our results show new electronic properties and semiconductor to metal transitions with pressure or traction
