High-quality single crystal diamond has been used to demonstrate the RF performance of hydrogenterminated diamond field effect transistors of varying gate lengths; this includes the first data on a sub100nm diamond transistor. The RF performance for 220nm, 120nm and 50nm gate length transistors was extracted and a cut-off frequency of 55 GHz was measured for the 50nm device. This is the highest...

Based on the non-equilibrium Green’s function formalism we numerically studied gate-controlled tunneling carbon nanotube field-effect transistors. The effect of doping concentration on the performance of the device has been investigated. We show that an asymmetric doping profile can improve the Ion/Ioff ratio of the device improves.

Organic field-effect transistors (OFETs) were first described in 1987. Their characteristics have undergone spectacular improvements during the last two or three years. At the same time, several models have been developed to rationalize their operating mode. In this review, we examine the performance of OFETs as revealed by recently published data, mainly in terms of field-effect mobility and o...

This paper reports a versatile nano-sensor technology using "top-down" poly-silicon nanowire field-effect transistors (FETs) in the conventional Complementary Metal-Oxide Semiconductor (CMOS)-compatible semiconductor process. The nanowire manufacturing technique reduced nanowire width scaling to 50 nm without use of extra lithography equipment, and exhibited superior device uniformity. These n ...

This chapter aims to provide the reader with a practical knowledge about electrical methods to measure organic thin film transistor devices. It presents a series of recipes, which allow the experimentalist to gain insight into the performance and limitations of the devices and circuits being measured. It also gives guidelines on how to correctly interpret the measurements and to provide feedbac...

Over the past twenty years, research into the applications of organic semiconductors (OSCs) has intensified rapidly. Though their electron mobility is much lower than that of typical semiconductors, OSCs show promise in low-cost, flexible, lightweight, and environmentally-friendly semiconductor applications. Their hole mobility was found to be comparable to that of amorphous silicon (a-Si), wit...

ἀ ere are several different types of field effect transistors (FETs), each of which has a different operational principle. For example, there are metal oxide semiconductor (MOS) transistors, junction field effect transistors (JFETs), static induction transistors (SITs), the punch-through transistors (PHTs), and others. All of these devices employ the flow of majority carriers. ἀ e most popular ...

The paper deals with an inverse problem of ion mixture composition estimation using electronic sensors based on conventional MOS transistors. The device sensitivity to various ions is obtained by replacing the traditional transistor gate structure by special polymer membranes, which are sensitive to the ions in an electrolyte flowing over the gate. Unfortunately, the membrane selectivity is lim...
