Microwave transmission loss in multi-walled nanotubes

Journal article

Experimental results for microwave transmission losses of individual multi-walled carbon nanotubes (MWNTs) are presented. Samples with MWNTs. as well as samples without MWNTs. were fabricated with two types of electrode materials (Nb vs. Cr/Au) and configurations to compare AC transmissions loss as passive devices at room temperature. In the MWNT-Nb sample, the transmitted current is higher and attenuation is lower than the MWNT-Cr/Au samples. However, the transmission loss increases much faster in the Nb samples than Cr/Au samples with increasing frequency. Overall, their S-parameter measurements from 0.5 GHz to 110 GHz support frequency-dependent microwave dissipation of the MWNTs and the metal-electrode contact. © 2008 WILEY-VCH Verlag GmbH and Co.
