Deterministic Synthesis of Carbon Nanotubes
Ali Javey, Hongjie Dai
A novel method is developed to enable the formation, positioning and patterning of individual metal nano-clusters with controllable and monodispersed sizes down to 1-2 nm-scale. Am…
Oxidation Resistant Germanium Nanowires: Bulk Synthesis, Long Chain Alkanethiol Functionalization and Langmuir-Blodgett Assembly
Dunwei Wang, Ying-Lan Chang, Zhuang Liu +1
A simple method is developed to synthesize gram quantities of uniform Ge nanowires (GeNWs) by chemical vapor deposition on preformed, monodispersed seed-particles loaded onto high…
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…
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…
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…
Advancements in Complementary Carbon Nanotube Field-Effect Transistors
Ali Javey, Qian Wang, Woong Kim +1
High performance p- and n-type single-walled carbon nanotube (SWNT) field-effect transistors (FETs) are obtained by using high and low work function metals, Pd and Al as source/dra…
