Abstract: The paper deals with the numerical simulation of Gunn diodes operation based on the graded-gap AlInN. We have obtained the output characteristics of diodes with different cathode contacts in a wide range of frequencies. Harmonic and biharmonic modes of operation have been considered. Cutoff frequency and minimum length of the active region have been estimated. Performances of graded-gap AlInN diodes are compared with the performances of InN and AlN diodes. [ABSTRACT FROM AUTHOR]
