Pure carbon bulk junctions are fabricated based on carbon nanotube (CNT) macrostructures and their electrical transport characteristics are investigated. The planar 1D/2D strand-on-film (SOF) junctions show interesting force- and light-controlled transport behaviors. Considering the excellent chemical stability and good mechanical properties (strength, hardness and elasticity) of CNTs, the SOF junctions could find practical and wide applications in electromechanical and optoelectronic devices.
