GaN-on-GaN power semis Power semiconductors based on gallium nitride (GaN) are heating up in the market. Typically, suppliers are shipping devices using a GaN-on-silicon process. These devices are available with blocking voltages of up to 650 volts. Going beyond 650 volts is problematic, however. GaN-on-silicon processes suffer from lattice mismatches, cost and other issues. At the ... » read more
