Elimination of kink phenomena and drain current hysteresis in InP-based HEMTs with a direct ohmic structure.

Elimination of kink phenomena and drain current hysteresis in InP-based HEMTs with a direct ohmic structure.

We eliminated kink phenomena and Ids hysteresis in a double-doped InP-based HEMT without degrading its frequency performance by fabricating direct ohmic contacts in the InGaAs channel. A direct ohmic structure lets us control current paths in the device and relax the electric field at the recess edg...
