A Comprehensive Review of Recent Progress, Prospect and Challenges of Silicon Carbide and its Applications

Schottky diode on Silicon Carbide (SiC): ideal detector for very wide temperature range sensors

“…Nowadays, Schottky Diode, MOSFET and JFET are the most popular SiC power devices in the market 2,3 . Firstly, the SiC Schottky Diode (SBD) already has almost 20 years of mature commercial exploitation since the beginning of this century.…”

“…The primary application areas for SiC Schottky diodes are in power factor correction circuits, power supplies, photovoltaic inverters and sensors [3][4][5][6][7][8][9][10][11][12][13][14] . The main advantage of the SBD is the practical absence of reverse recovery current during switching, hence it is possible to increase the switching frequency considerably.…”

Thermal Transport of AlN/Graphene/3C-SiC Typical Heterostructures with Different Crystallinities of Graphene

“…Meanwhile, the high conductivity of SiC allows the preparation of vertical GaN-based LED chips with uniform current distribution density to avoid local overheating problems. 10 In addition, the small thermal mismatch and lattice mismatch between AlN and GaN make the former a buffer layer for the preparation of InGaN-based high-power blue LEDs, 11 high electron mobility transistors, 7 photodetectors, 12 and laser diodes. 13 Furthermore, AlN has good transparency in the ultraviolet (UV) region and is suitable for the fabrication of AlGaN-based deep UV LEDs.…”

“…The lower lattice mismatch between SiC and GaN and the high thermal conductivity of SiC make it a suitable substrate for GaN-based blue LEDs due to the lack of a natural GaN direct substrate. Meanwhile, the high conductivity of SiC allows the preparation of vertical GaN-based LED chips with uniform current distribution density to avoid local overheating problems . In addition, the small thermal mismatch and lattice mismatch between AlN and GaN make the former a buffer layer for the preparation of InGaN-based high-power blue LEDs, high electron mobility transistors, photodetectors, and laser diodes .…”

“…Currently, interfacial layers, − nanoscale interfacial structures, − interfacial modifications, − and high pressures are effective ways to enhance heat transfer in typical heterostructures. Among them, graphene with a thermal conductivity of up to 3000 W/m·K has received much attention as an interfacial layer introduced inside electronic/optoelectronic chips to reduce thermal resistance. − Han et al embedded a layer of reduced graphene oxide in GaN-based high-power LED chips. It was shown that under high temperature and high operating current conditions, reduced graphene oxide makes the junction temperature of the LED reduced by about 17 °C.…”
