摘要：
Creation of large-scale arrays of single-walled carbon nanotubes (SWNTs) with defined orientation and density is of central importance for obtaining functional electronic device structures that incorporate these nanoscaled systems. This manuscript describes how the macroscopic electrical properties of 2D SWNT networks vary controllably with the microscopic alignment individual SWNTs in the network. These studies indicate that "orthogonal" SWNT structures provide enhanced reproducibility and conductivity, when compared to deposits of highly aligned SWNTs. Because this material is composed of a submonolayer coverage of SWNTs, such deposits have applications in flexible and transparent electronic materials.
