Electrothermal modeling of single-walled carbon nanotube (SWCNT) field-effect transistor (FET) is performed in this paper, with special attention focused on its self-heating effect. The method of finite difference is implemented for solving a 1-D heat conduction equation in the semiconducting channel self-consistently, and its nonuniform temperature distribution is evaluated for 20-, 32-, and 45-nm...
Electrothermal characterization of single-walled carbon nanotube (SWCNT) field effect transistors (CNTFETs) is performed in this paper. By solving one-dimensional heat conduction equation in the channel self-consistently, self-heating effects on the I-V characteristics, signal delay and cutoff frequency of the CNTFET are studied. Simulated results indicate that the performance degradation of the CNTFET,...
Various silicon-based microchannels with different internal surface morphology is investigated to grow CNTs (carbon nanotubes) on the surface of the pore wall which may enhance the electron emission. The morphology of the samples prepared under different conditions is determined by scanning electron microscopy (SEM). Parameters such as temperature, concentration of hydrofluoric acid, potential, current...
Bundled double-walled and multi-walled carbon nanotubes (DWNT and MWNT) are effectively dispersed under a long-time sonication in the presence of polystyrene (PS) and poly(vinyl alcohol) (PVA), by the means of non-covalent functionalization. FTIR and Raman reveals an interactions between CNTs and polymers, and the helical wrapping is clearly observed by HRTEM. By dint of template with nanopores and...
