摘要
The performance of 50nm gate length GaN/AlGaN HEMTs is reported. The device layers were grown by MBE directly onto an SiC substrate. Devices exhibit a maximum drain current density of 1.2A/mm. an extrinsic f(tau) of 110GHz and an f(max) of over 140GHz. The f(tau), of 110GHz is the highest reported to date for a GaN/AlGaN HEMT, a nearly 50% increase over the previous record.
