Simply including either single ferroelectric oxide layer or threshold selector, we can make conventional field effect transistor to have super steep switching characteristic, i.e., sub-60-mV/decade of subthreshold slope. One of the representative is negative capacitance FET (NCFET), in which a ferroelectric layer is added within its gate stack. The other is phase FET (i.e., negative resistance ...
We have investigated the effect of deoxyribonucleic acid (DNA) adsorption on a graphene field-effect-transistor (FET) device. We have used graphene which is grown on a Ni substrate by chemical vapour deposition. The Raman spectra of our graphene indicate its high quality, and also show that it consists of only a few layers. The current-voltage characteristics of our bare graphene strip FET show...
In this paper review study on different types of Junctionless transistor is promoted. Here a comparative study of SOI, bulk planar, double gate and tunnel Junctionless field effect transistor. It is observed Junctionless transistor exhibits better short channel effects and ON current then inversion mode device. Tunnel Junctionless transistor exhibits the properties of both tunnel FET and Juncti...
Design and fabrication of electronic biosensors based on field-effect-transistor (FET) devices require understanding of interactions between semiconductor surfaces and organic biomolecules. From this perspective, we review practical considerations for electronic biosensors with emphasis on molecular passivation effects on FET device characteristics upon immobilization of organic molecules and a...
The existing health care systems focus on treating diseases rather than preventing them. Patients are generally not tested unless physiological symptoms are appeared. When they do get tested, the results often take several days and can be inconclusive if the disease is at an early stage. In order to facilitate the diagnostics process and make tests more readily available for patients, the conce...
– A new type of NO2 gas sensor has been made using the Floating Gate Field Effect Transistor (FG-FET) sensor system. 200 nm ZnO films were deposited on Si/Ti/Pt electrodes, which are mounted on FG-FET chips. SEM and EDX characterization methods were employed to study the surface of these films. The change in the work function of the film due to their interaction with NO2 has been measured at va...
The Field Effect Transistor (FET) is today the basic element of Very Large ScaIe Integrated (VLSI) digital systems. FETs are also used in analog circuits for high frequency (microwave) applications. Different types of FETs are the Metal Oxide Semiconductor Field Effect Transistors (MOSFETs), the MEtal Semiconductor Field Effect Transistors (MESFETs) and the MOdulation Doped Field Effect Transis...
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.
