One of the main factors that impacts the efficiency of solar cells is due to the scattering of electrons inside the cells. Carbon nanotubes (CNTs) have proposed to use in solar cells due to their ballistic transport properties: electrons travel through CNTs without experiencing scattering or experiencing negligible scattering. The conductance of CNTs is shown to be quantized and has a multiple ...

We study the effect of mesoscopic fluctuations on the validity of the Wiedemannn-Franz WF law for quasi-one-dimensional metal wires and open quantum dots. At temperatures much less than the generalized Thouless energy, Ec, the WF law is satisfied for each specific sample, but as the temperature is raised through Ec, a sample-specific correction to the WF law of order 1/g appears g is the dimens...

Abstract Electrical characterization of nanostructures, such as nanotubes and wires, is a demanding task that vital for future applications nanomaterials. The nanostructures should ideally be analyzed in free-standing state also allow other material characterizations to made the same individual nanostructures. Several methods have been used electrical carbon past. results are widely spread, bot...
