Abstract:

Devices including nano-junctions made between aligned functionalized carbon nanotubes, and methods of aligning functionalized carbon nanotubes for the purpose of fabricating either coaligned or criss-crossed p-n junctions. Devices, such as thermoelectric devices, may be formed of a plurality of n-type carbon nanotubes forming a film and/or a plurality of p-type carbon nanotubes forming a film. Methods of making a criss-crossed p-n nanojunction device include the steps of functionalizing a carbon nanotube to create a p-type tube, functionalizing a carbon nanotube to create an n-type tube, applying an RF field to align nanotubes of a given p- or n-type, and orienting nanotubes of different types cross-wise relative to each other to achieve criss-crossed p-n nanojunctions.
