Note:
explanatory comparison of the basic operational behaviour of rectifier diodes and Gallium Arsenide
Schottky diodes:
conduction
forward characteristics
turn off characteristics
turn on characteristics
by majority + minority carriers
V
(I
)
extraction of excess carriers
causes temperature dependant
reverse recovery (t

, Q
)
delayed saturation leads to V
