Chemical Self Assembly of Graphene Sheets
Hailiang Wang, Xinran Wang, Xiaolin Li +1
Chemically derived graphene sheets were found to self-assemble onto patterned gold structures via electrostatic interactions between noncovalent functional groups on GS and gold. T…
Optical Characterizations and Electronic Devices of Nearly Pure (10,5) Single-Walled Carbon Nanotubes
Li Zhang, Xiaomin Tu, Kevin Welsher +3
It remains an elusive goal to achieve high performance single-walled carbon nanotube (SWNTs) field effect transistors (FETs) comprised of only single chirality SWNTs. Many separati…
Hydrogenation and Hydro-Carbonation and Etching of Single-Walled Carbon Nanotubes
Guangyu Zhang, Pengfei Qi, Xinran Wang +4
We present a systematic experimental investigation of the reactions between hydrogen plasma and single-walled carbon nanotubes (SWNTs) at various temperatures. Microscopy, infrared…
DNA Functionalization of Carbon Nanotubes for Ultra-Thin Atomic Layer Deposition of High k Dielectrics for Nanotube Transistors with 60mV/decade Switching
Yuerui Lu, Sarunya Bangsaruntip, Xinran Wang +3
For single-walled carbon nanotube (SWNT) field effect transistors, vertical scaling of high k dielectrics by atomic layer deposition (ALD) currently stands at ~8nm with subthreshol…
