Spectral Domain Z-scan Technique
Xi Zeng, Pengfei Qi, Pin Chen +2
Characterizing the nonlinear optical properties of various materials plays a prerequisite role in nonlinear optics. Among different methods, the well-known Z-scan technique and the…
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…
10 to 50 nm Long Quasi Ballistic Carbon Nanotube Devices Obtained Without Complex Lithography
Ali Javey, Pengfei Qi, Qian Wang +1
A simple method combining photolithography and shadow (or angle) evaporation is developed to fabricate single-walled carbon nanotube (SWCNT) devices with tube lengths L~10-50 nm be…
Miniature Organic Transistors With Carbon Nanotubes as Quasi-One Dimensional Electrodes
Pengfei Qi, Ali Javey, Marco Rolandi +3
As the dimensions of electronic devices approach those of molecules, the size, geometry and chemical composition of the contact electrodes play increasingly dominant roles in devic…
