Experimental 4H-SiC junction-barrier Schottky (JBS) diodes
- Russian Academy of Sciences, Ioffe Physicotechnical Institute (Russian Federation)
4H-SiC junction-barrier Schottky (JBS) diodes have been fabricated with local p-n junctions under the Schottky contact formed by nonequilibrium diffusion of boron. Static and dynamic characteristics of the JBS diodes are compared with those of similar 4H-SiC Schottky diodes. It is shown that, compared with ordinary Schottky diodes, the JBS diodes have leakage currents that are, on average, a factor of 200 lower at the same reverse bias. The reverse recovery charge is the same for both types of diodes and equal to the charge of majority carriers removed from the n-type base region in switching.
