Mechanical and electrical contact resistance characteristics of a cellular assembly of carbon nanotubes

Mangalampalli, S.R.N. Kiran; Ramamurty, U; Misra, Abha


We employ nanoindentation coupled with electrical contact resistance measurements for simultaneous characterization of the electrical and mechanical behaviors of a cellular assembly of carbon nanotubes (CNTs). Experimental results reveal two different responses that correspond to relatively dense and porous regions of the cellular structure. Distinct nonlinear electron transport characteristics are observed, which mainly originate from diffusive conductance in the CNT structure. In the denser...[Show more]
