Thermal and Thermoelectric Properties
Graphite and diamond show extraordinary heat capacity and thermal conductivity. It can be expected that nanotubes have similar thermal properties at room and elevated temperatures but unusual behavior at low temperatures because of the effects of phonon quantization. Both theory and experiment show that intertube coupling in SWNT bundles and MWNTs is weak in temperature region of gt 100 K 85 . The specific heat of MWNTs has not been examined theoretically in detail. Experimental results on...
Atomic Force and Scanning Tunneling Microscopy
The previous section demonstrated the usefulness of EM techniques applied to nanotube research. However, there are two other microscopic methods that are indispensable in nanotube research. These methods are atomic force microscopy AFM and scanning tunneling microscopy STM . Both methods have provided important information of nanotube structure and properties. AFM has been very useful in imaging isolated SWNTs that have either been grown directly on silicon substrates via a chemical vapor...
Structure and Microstructure of CNT Field Emitters
Carbon nanotubes have been shown to have excellent emission characteristics emission has been observed at fields lower than 1 V m, and high current densities of over 1 A cm2 have been obtained. Detailed reviews of the properties of CNT as field emitters can found in the literature 6,7 . CNT emitters can be fabricated in a variety of configurations depending on the nature of the nanotubes, their microscopic arrangement, the preparation process, and the desired emitter structure. Field emission...
