Comment on ‘Magnetoresistance and differential conductance in mutliwalled carbon nanotubes’

چکیده
Jeong-O Lee el al. [Phy. Rev. B, 61, R16 362 (2000)] reported magnetoresistance and differential conductance measurements of multiwalled carbon nanotubes. The observed aperiodic conductance fluctuations and the negative magnetoresistance was interpreted to originate exclusively from changes in the density of states at the Fermi energy. We show that this interpretation is questionable and not supported by their measurements. 73.23.-b, 72.80.Rj, 73.50.Jt, 73.61.Wp, 73.20.Fz Typeset using REVTEX

Spin transport in disordered single-wall carbon nanotubes contacted to ferromagnetic leads
Recent conductance measurements on multi-wall carbon nanotubes (CNTs) reveal an effective behavior similar to disordered single-wall CNTs. This is due to the fact that electric current flows essentially through the outermost shell and is strongly influenced by inhomogeneous electrostatic potential coming from the inner tubes. Here, we present theoretical studies of spin-dependent transport thro...
متن کاملEffect of scattering and contacts on current and electrostatics in carbon nanotubes
We computationally study the electrostatic potential profile and current carrying capacity of carbon nanotubes as a function of length and diameter. Our study is based on solving the nonequilibrium Green’s function and Poisson equations self-consistently, including the effect of electron-phonon scattering. A transition from the ballistic to diffusive regime of electron transport with an increas...
متن کاملSpin effects in single electron tunneling
An important consequence of the discovery of giant magnetoresistance in metallic magnetic multilayers is a broad interest in spin dependent effects in electronic transport through magnetic nanostructures. An example of such systems are tunnel junctions – single-barrier planar junctions or more complex ones. In this review we present and discuss recent theoretical results on electron and spin tr...
متن کاملTheoretical studies of spin-dependent electrical transport through carbon nanotbes
Spin-dependent coherent quantum transport through carbon nanotubes (CNT) is studied theoretically within a tight-binding model and the Green’s function partitioning technique. End-contacted metal/nanotube/metal systems are modelled and next studied in the magnetic context, i.e. either with ferromagnetic electrodes or at external magnetic fields. The former case shows that quite a substantial gi...
متن کاملMagnetoresistance devices based on single-walled carbon nanotubes.
We demonstrate the physical principles for the construction of a nanometer-sized magnetoresistance device based on the Aharonov-Bohm effect [Phys. Rev. 115, 485 (1959)]. The proposed device is made of a short single-walled carbon nanotube (SWCNT) placed on a substrate and coupled to a tip/contacts. We consider conductance due to the motion of electrons along the circumference of the tube (as op...
