The meaning of FIELD-EFFECT TRANSISTOR is a transistor in which the output current is controlled by a variable electric field.
The advantages of power field-effect transistors over bipolar transistors are: (1) Field-effect transistors have faster switching speeds with reduced delay, rise, storage, and fall times. (2) Devices are voltage controlled rather than current controlled and can be driven from logic-level signals....
Field-effect transistors exist in two major classifications. These are known as thejunction FET (JFET)and themetal-oxide- semiconductor FET (MOSFET). The junction FET has a channel consisting of N-type semiconductor (N-channel) or P-type semiconductor (P-channel) material; the gate is made o...

Biosensors based on field-effect transistors (FETs) have attracted much attention, as they offer rapid, inexpensive, and label-free detection. While the lo... D Sarkar,W Liu,X Xie,... - 《Acs Nano》 被引量: 325发表: 2014年 Molecular Ordering of High-Performance Soluble Molecular Semiconduc...
Since the 1960s, the feature size of metal oxide semiconductor field-effect transistors has been scaled down to sub-micrometer and even nanometer to increase the transistor density on a chip according to the Moore’s law, leading to smaller device, faster speed and lower power consumption. In...
Here we demonstrate the potential of carbon-nanotube-based single-molecule field-effect transistors (smFETs), which can detect the charge on a single molecule, as a new platform for recognizing and assaying small molecules. smFETs are formed by the covalent attachment of a probe molecule, in ...
(THz) domain, ac-to-dc conversion by conventional electronics becomes challenging and requires alternative rectification protocols. Here, we address this challenge by tunnel field-effect transistors made of bilayer graphene (BLG). Taking advantage of BLG’s electrically tunable band structure, we ...
Field-effect transistors are divided into two categories: junction field-effect transistors (JFET) and metal oxide semiconductor field-effect transistors(MOSFET). According to the channel material type and insulated gate type, there are N channel and P channel transistors; According to the conducti...
