Temperature and Gas-Environment Dependent Electron and Phonon Transport in Suspended Carbon Nanotubes Up to Electrical Breakdown
David Mann, Eric Pop, Jien Cao +3
High bias electrical transport characteristics of freely suspended metallic single-walled carbon nanotubes (SWNTs) are investigated at 250-400K in vacuum and various gases. Self-he…
On the Origin of Preferential Growth of Semiconducting Single-Walled Carbon Nanotubes
Yiming Li, Shu Peng, David Mann +4
A correlation is observed between the diameter (d) distribution of single walled carbon nanotubes and the percentages of metallic and semiconducting tubes in materials synthesized…
Surface Chemistry and Electrical Properties of Germanium Nanowires
Dunwei Wang, Ying-Lan Chang, Qian Wang +4
Germanium nanowires with p- and n-dopants were synthesized by chemical vapor deposition and used to construct complementary field effect transistors . Electrical transport and x-ra…
Suspended Carbon Nanotube Quantum Wires with Two Gates
Jien Cao, Qian Wang, Dunwei Wang +1
Suspended single-walled carbon nanotube devices comprised of high quality electrical contacts and two electrostatic gates per device are obtained. Compared to nanotubes pinned on s…
