Quantized Electrical Conductance of Carbon nanotubes(CNTs)
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 ...
متن کاملQuantum conductance steps in solutions of multiwalled carbon nanotubes.
We have prepared solutions of multiwalled carbon nanotubes in Aroclor 1254, a mixture of polychlorinated biphenyls. The solutions are stable at room temperature. Transport measurements were performed using a scanning-tunneling probe on a sample prepared by spin coating the solution on gold substrates. Conductance steps were clearly seen. A histogram of a high number of traces shows maximum peak...
متن کاملMultiwalled Carbon Nanotubes: Environmental Application
The high external surface area leads to a significant increase in the surface contact between the gaseous or liquid reactants and the active phase supported on this nanostructured host which is a prerequisite for its use as catalyst support, especially in liquid phase medium where diffusion rate is predominant [2]. Also, the strong interactions between the exposed prismatic planes and the depos...
متن کاملLithiation-induced embrittlement of multiwalled carbon nanotubes.
Lithiation of individual multiwalled carbon nanotubes (MWCNTs) was conducted in situ inside a transmission electron microscope. Upon lithiation, the intertube spacing increased from 3.4 to 3.6 Å, corresponding to about 5.9% radial and circumferential expansions and ∼50 GPa tensile hoop stress on the outermost tube wall. The straight tube walls became distorted after lithiation. In situ compress...
متن کاملThermal conductivity of individual multiwalled carbon nanotubes
Thermal conductivity of individual multiwalled carbon nanotubes (MWCNT) is measured using a pulsed photothermal reflectance technique. Intrinsic thermal conductivity of individual MWCNT with a diameter 150 nm and length 2 mm at room temperature is extracted to be 2586 W/mK. Individual MWCNT is surrounded by SiO2, so parallel resistor model is applied in which SiO2 supportive is treated as a con...
