چکیده

After a long period of mainly static application of ISFETS, other more sophisticated applications are now being developed, based on the exploitation of the dynamic properties of ISFETS. Examples are the use of flow-through cells with sample injection and the integration of a p H actuator electrode for very fast titration in a microvolume. Also, the most recent development of an immunoFET makes use of induced transient phenomena.

Representation of the temperature nano-sensors via cylindrical gate-all-around Si-NW-FET

In this paper, the temperature dependence of some characteristics of cylindrical gate-all-around Si nanowire field effect transistor (GAA-Si-NWFET) is investigated to representing the temperature nano-sensor structures and improving their performance. Firstly, we calculate the temperature sensitivity of drain-source current versus the gate-source voltage of GAA-Si-NWFET to propose the temperatu...

Theory and application of the material work function for chemical sensors based on the field effect principle

This paper gives first of all the definition of the work function of an electronic as well as an ionic conductor. FET-type gas sensors known from the literature are considered in view of this basic theory and the parameter of the work function which is responsible for the sensing properties is noticed. This appears not always to be possible for the various types of gas sensors, in this case the...

Development of SiC-FET methanol sensor

A silicon carbide based field effect transistor (SiC-FET) structure was used for methanol sensing. Due to the chemical stability and wide band gap of SiC, these sensors are suitable for applications over a wide temperature range. Two different catalytic metals, Pt and Ir, were tested as gate contacts for detection of methanol. The sensing properties of both Ir gate and Pt gate SiC-FET sensors w...
