Investigations of Tunneling for Field Effect Transistors

We have fabricated field effect transistors in order to study charge trapping in pentacene transistors and charge noise in a variety of organic field effect transistors.

The IGFET or MOSFET is a voltage controlled field effect transistor that differs from a JFET in that it has a “Metal Oxide” Gate electrode which is electrically insulated from the main semiconductor n-channel or p-channel by a very thin layer of insulating material usually silicon dioxide, commonly known as glass. This ultra thin insulated metal gate electrode can be thought of as one plate of ...

The combination of their electronic properties and dimensions makes carbon nanotubes ideal building blocks for molecular electronics. However, the advancement of carbon nanotube-based electronics requires assembly strategies that allow their precise localization and interconnection. Using a scheme based on recognition between molecular building blocks, we report the realization of a self-assemb...

Novel type of a field effect transistor (FET) is described. A metallic channel of a metallic nanotube FET is proposed to be switched ON/OFF by applying electric fields of a local gate. Very inhomogeneous electric fields may lower the nanotube symmetry and open a band gap, as shown by tight–binding calculations.

This research paper explains the effect of dimensions Gate-all-around Si nanowire tunneling field transistor (GAA Si-NW TFET) on ON/OFF current ratio, drain induces barrier lowering (DIBL), sub-threshold swing (SS), and threshold voltage (VT). These parameters are critical factors characteristics tunnel transistors. The Silvaco TCAD has been used to study electrical TFET. Output (gate voltage-d...

was readily constructed by simple modification of a common FID hydrocarbon monitor, with addition of a commercially available valve oven, switching valve, and timer. This system, except for the adjusted response time, had virtually the same operating specifications as the original hydrocarbon analyzer. Short-term studies indicated the system was practical, reliable, and accurate. Air-monitoring...

In nature, electrical signalling occurs with ions and protons, rather than electrons. Artificial devices that can control and monitor ionic and protonic currents are thus an ideal means for interfacing with biological systems. Here we report the first demonstration of a biopolymer protonic field-effect transistor with proton-transparent PdH(x) contacts. In maleic-chitosan nanofibres, the flow o...
