An advanced step-graded Gunn diode (~ 100 GHz fundamental frequency) has been developed using a joint modelling-experimental approach to test GaAs based Gunn oscillators at sub-millimetre wavelengths. These devices are to be used as high power (multi-mW) Terahertz sources in conjunction with multipliers using Schottky diodes as the non-linear elements. The modelled-measured results of low series resistance Schottky diodes with non-alloyed contacts are also discussed.
