Fig. 20.9. Room temperature drain current e vs. drain-source voltage VDS characteristics at various gate voltages VG 0, 30, 40, 50, 60 V for a fullerene-derived field effect transistor with conduction in an -type C60 C70 channel induced at the SiO2-C l0 interface 20.49 , A schematic diagram for the device is shown in Fig. 20.8 b . that the fullerene transistors are -channel devices, consistent with C60 anion formation. Field effect mobilities of up to 0.08 cm2 V s were obtained from the ID-VDS...

Fig. 19.35. Dependence on tubule circumference of the magnetic moment closed circles and magnetic susceptibility triangles of carbon nanotubes calculated according to the k - p approximation for H tubule axis and 0 1 6 and a0 0.246 nm. The magnetic moment calculated according to the tight binding model is given by open circles. The magnetic moment is independent of the circumference l, except for very small diameter tubes 19.119 , 30 A. Also for the semiconducting tubules, the magnetic moment...

Infrared and Raman spectroscopies show many more lines for the pressure-induced C60 phases than for conventional C60 7.128 , consistent with the loss of icosahedral Ih symmetry for the C60 molecule in both of these high-pressure phases. A structural model shows that the C60-C60 distance in the pressure-induced phases becomes close enough to form a chemical bond for the fcc pC60 and rh pC60 phases, consistent with the reduced solubility of the pressure-induced phases in toluene and...
