Ph. Ladbrooke et Jp. Bridge, BENIGN MECHANISM GIVING RISE TO KINKS IN GAAS-MESFET AND HEMT I(V) CHARACTERISTICS, Electronics Letters, 31(22), 1995, pp. 1947-1948
Kinks in GaAs MESFET and HEMT I(V) characteristics may arise from a ch
ange in the depletion layer dimensions caused by redistribution of the
two-dimensional electric field when the space-charge layer reaches th
e drain-side recess edge. The mechanism is benign in that it does not
question material quality and growth.
