The MESFET, similarly to JFET, differs from the common insulated gate FET or MOSFET in that there is no insulator under the gate over the active switching region. This implies that the MESFET gate should, in transistor mode, be biased such that one has a reversed-biased depletion zone controlling the underlying channel, rather than a forward-conducting metal–semiconductor diode to the channel.

Silicon carbide (SiC) [Lange, 27] says this material is uncommon and costs 20-100 times as much as alumina. “It has good flexural strength and toughness” and has good thermal properties.
Gate oxide degradation of SiC MOSFET under short …
1/9/2016· The SiC MOSFET transistor is considered as a relatively robust switch under short-circuit tests. In  , authors highlighted the device robustness dependency on the test conditions. Indeed, increasing the drain bias, the gate bias or the case temperature gives rise to a higher power dissipation, hence a die''s temperature increase, thereby limiting the transistor stamina under short-circuit mode.

In recent years, GaN (gallium nitride) and SiC (silicon Carbide) based semiconductors called the "Next Generation Power Semiconductors"have been receiving much attention. Compared to silicon, GaN and SiC have a wider band gap (Si:1.1, SiC:3.3, GaN:3.4), and therefore it is also called "Wide Band Gap Semiconductors".

Semiconductor device - Wikipedia
A semiconductor diode is a device typically made from a single p–n junction. At the junction of a p-type and an n-type semiconductor there forms a depletion region where current conduction is inhibited by the lack of mobile charge carriers. When the device is forward biased (connected with the p-side at higher electric potential than the n-side), this depletion region is diminished, allowing

Field-effect transistor — Wikipedia Republished // WIKI 2
The field-effect transistor (FET) is a transistor that uses an electric field to control the electrical behaviour of the device. FETs are also known as unipolar transistors since they involve single-carrier-type operation. Many different implementations of field effect transistors exist. Field effect transistors generally display very high input impedance at low frequencies. The conductivity
