Single-wall carbon nanotube (SWCNT) species as materials display exceptional nanotube-structure specific optical properties of interest to sensing devices, quantum material use as single photon sources, terahertz applications and photonic structures.  The directed assembly of individual SWCNTs onto device structures or into 2D and 3D crystalline arrays is required for such applications.  Both research into specific assembly methods of SWCNT structures (aligned films, arrays of individualized SWCNTs) and the characterization of assembly success and emergent or structure-dominated optical behaviors are of interest.
