Subbands in Carbon Nanotubes under Radial Deformation
Carbon nanotubes, which consist of only carbon atoms, were first discovered by Iijima [1] and can be thought of as a single layer of graphite that is wrapped into a cylinder. The cylindrical nanotubes are very stable and are regarded as the strongest fibers ever; nanotubes are extremely rigid to distortions along the tube axis whereas they are very flexible to those perpendicular to the axis [2...
متن کاملTransport Properties For Carbon Nanotubes Under Hydrostatic Pressure
Multi-wall carbon nanotubes (MWNTs) were mixed with polystyrene (PS) by 20 wt%, which is slightly above the percolation threshold. Temperature (T ) dependencies of Seebeck coefficient (S) and resistance (R) for the sample (MWNT-PS) were measured under hydrostatic pressure upto 1.2 GPa. The resistance at ambient pressure showed power law T -dependence (R ∝ T−α) and agreed well with Luttinger liq...
متن کاملTheoretical analysis on electronic properties of zigzag-type single-walled carbon nanotubes under radial deformation
Carbon nanotubes (CNTs) have been attracting attention because they have characteristic mechanical and electronic properties. It has been reported that single-walled CNTs can induce large deformation without bond breaking. Therefore, it is of interest to elucidate the electronic properties of CNTs under large deformation. We investigate the deformation behavior and the change in the electronic ...
متن کاملMultiple radial corrugations in multiwalled carbon nanotubes under pressure.
Radial elastic corrugation of multiwalled carbon nanotubes under hydrostatic pressure is demonstrated by using the continuum elastic theory. Various corrugation patterns are observed under a pressure of several GPa, wherein the stable cross-sectional shape depends on the innermost tube diameter D and the total number N of concentric walls. A phase diagram is established to obtain the requisite ...
متن کاملLow pressure adsorption of CO2 on multi-wall carbon nanotubes
Volumetric techniques were employed to study the adsorption of CO2 on a purified multi-wall carbon nanotubes (MWNT’s) sample, as a mesoporous material, at isothermal conditions of 288, 293 and 298 K and pressures ranging from 30 to 150 kPa. Langmuir, Freundlich and Sips equations were used to represent the isotherms. Also the parameters of these fitted isotherm models have been determined. The ...
