A silicon carbide bipolar junction transistor with novel emitter field plate (EFP-BJT) design is proposed in this paper. The fabried EFP-BJT features a metal plate of the extending emitter electrode with a 50-nanometer-thick oxide layer overlapped on the extrinsic base surface. The contrast of experimental results show that a 56% increase of maximum current gain is obtained by the EFP-BJT
Indeed, the higher thermal conductivity of silicon carbide, (three times more than silicon), permits better heat dissipation and allows better cooling and temperature management. Though many temperature sensors have already been published, little endeavours have been invested in the study of silicon carbide junction field effect devices (SiC-JFET) as a temperature sensor.

Appliions, Prospects and Challenges of Silicon Carbide Junction Field Effect Transistor (SIC JFET) Properties of Silicon Carbide Junction Field Effect Transistor (SiC JFET) such as high switching speed, low forward voltage drop and high temperature operation have attracted the interest of power electronic researchers and technologists, who for many years developed devices based on Silicon (Si).
The SiC cascode has already taken a leading role in realizing the advantages of silicon carbide in important power-conversion appliions, including renewable energy generation, transportation, consumer tech and smart industry.

Silicon carbide (SiC) exhibits excellent material properties attractive for broad appliions. We demonstrate the first SiC optomechanical microresonators that integrate high mechanical frequency
Switching losses for two silicon diodes (a fast diode, 600 V, 50 A, 60 ns Trr), an ultrafast silicon diode (600 V, 50 A, 23 ns Trr), and a 4H-SiC diode (600 V, 50 A) are compared. The effect of diode reverse recovery on the turn-on losses of a fast insulated gate bipolar transistor (IGBT) are studied both at room temperature and at 150 /spl deg/C.
The amplifier, which features a gallium nitride (GaN) transistor on a silicon (Si) substrate instead of a more costly silicon carbide (SiC), achieves a conversion efficiency rating of 70%, unprecedented among 2GHz power amplifiers with outputs of 150W or higher.
Help could be on the way from a gallium oxide-based transistor under development at the University at Buffalo. In a study published in the June edition of IEEE Electron Device Letters , electrical engineers describe how the tiny electronic switch can handle more than 8,000 volts, an impressive feat considering it’s about as thin as a sheet of paper.
