Electrical measurements of individual semiconducting single-walled carbon nanotubes of various diameters

Individual semiconducting single-walled carbon nanotubes ~SWNTs! of various diameters are studied by electrical measurements. Transport through a semiconducting SWNT involves thermal activation at high temperatures, and tunneling through a reverse biased metal–tube junction at low temperatures. Under high bias voltages, current–voltage (I – V) characteristics of semiconducting SWNTs exhibit pro...

Investigation of the Performance of Carbon Nanotube and Silicon Nanowire Junctionless Transistors using First–Principle Calculations

In this work, we present atomic scale simulation of junctionless semiconducting single–walled carbon nanotubes field effect transistors (CNT–FETs) and compare their performance to silicon nanowire (SiNW) transistors with similar dimensions. The energy dispersions relations for p–type SiNW and CNT are compared. The response of the transistors to source–drain bias and gate voltage is explored. Co...

Novel nanotube-on-insulator (NOI) approach toward single-walled carbon nanotube devices.

We present a novel nanotube-on-insulator (NOI) approach for producing high-yield nanotube devices based on aligned single-walled carbon nanotubes. First, we managed to grow aligned nanotube arrays with controlled density on crystalline, insulating sapphire substrates, which bear analogy to industry-adopted silicon-on-insulator substrates. On the basis of the nanotube arrays, we demonstrated reg...
