Abstract : The work performed under this proposal was primarily that by Professor Eric Pop. Professor Pop left Illinois for a faculty position at Stanford, at which point Professor Joseph Lyding took over as Illinois PI. Professor Lyding helped manage the Pop group remaining at Illinois after Professor Pop left, and he engaged in a collaborative effort with the Pop group to develop a selective thermal treatment process to improve the performance of carbon nanotube array transistors. Such transistors suffer about two orders of magnitude performance penalty due to high nanotube-nanotube resistances in the current pathways from source to drain. Thus, under normal operation CNT array transistors dissipate most of their energy at the inter-nanotube junctions. We developed an approach, termed nanosoldering that uses joule heating to selectively metallize the nanotube-nanotube junctions thereby reducing junction resistance and improving overall device characteristics.
