Carbon nanotubes are ideal one-dimensional conductors whose electronic properties are being studied in anticipation of microelectronic applications.  Our project focuses on the high frequency response of the nanotubes.  We built microcircuits via photolithography processes for studying single walled carbon nanotubes.  The nanotube catalyst pads were laid down using a positive photoresist process, the nanotubes were grown using chemical vapor deposition techniques, and the metal circuit pattern was laid down with a negative photoresist process. These devices will make it possible to investigate the  absorption of single carbon nanotubes as a function of frequency.
