Latest Patents

Chengkai Wu holds a patent for a Double Schottky-barrier diode. This invention includes a semi-insulating substrate, a left mesa, a middle mesa, and a right mesa, all formed by growth and etching on the substrate. The design features two anode probes and two air-bridge fingers. The two Schottky contacts are closely fabricated on the middle mesa in a back-to-back manner, which allows for even symmetric C-V characteristics and odd symmetric I-V characteristics. The output of a frequency multiplier using this diode only produces odd harmonics, making it suitable for high-order frequency multipliers. The cathodes of the two Schottky contacts are connected by a buffer layer without ohmic contact.
