ISFET is an ion-sensitive field-effect transistor used to measure ion concentrations in solution and is a new type of miniaturised semiconductor chemical sensor. It is based on the structure of the metal-insulator-semi-conductor field-effect transistor (MISFET) in which a metal gate is replaced by an ion selective membrane, an electrolyte and a reference electrode here when the ion concentration (such as pH) changes, the current through the transistor will change accordingly. Here, the solution is used as the gate electrode. A voltage between s ....etc

Abstract
The proper design and simulation of modern electronic microsystems oriented towards environment monitoring requires accurate models of various ambient sensors. In particular, this paper presents a comprehensive model of an ion sensitive eld effect transistor (ISFET). The model can be employed straightforwardly for simulations at device, circuit or system level. First, the model was validated with electrical measurements and simulatio ....etc

Strong Field-Effect in Graphene on SiC



Graphene, consisting of monolayer thick carbon, can be produced as an isolated layer (exfoliated graphite) or as an epitaxial layer on a SiC(0001) surface. We have used the latter method to produce graphene on 4H-SiC by heating at 1300 C in ultra-high vacuum with in-situ monitoring by electron diffraction. The graphene formation is performed at CMU, while transistor fabrication (with 1.5x0.5 mm2 channel area) is performed at Sarnoff Corp. A ....etc

This article describes the effect of tower displacement of two parallel transmission lines on the magnetic field distribution. Here, two parallel lines with the same working voltage and having the same span and in which the use of artificial tower displacement is made is modeled.Parallel transmission lines with different span lengths and different voltages produce tower displacements naturally and this is also modeled. Additionally, the effects like the spacing between the parallel lines, phase conductors arrangements and the transmission line ....etc

Prospect of P3HT Field effect transistors



Ohmic contact

Metal semiconductor contacts having a linear I-V characteristic in both biasing directions .
Ideally, Showing minimum contact resistance.
There will be no depletion width.
Ideally, Built-in potential is zero.
Electron flow between metal and semiconductor, Potential barrier is small and easily overcome by the application of small voltage.

Conclusion

P3HT FET hole mobility is still 0.1 cm2 /V s, Compar ....etc
