Electrical breakdown on surface passivated semi-insulating GaAs substrates is shown to be accompanied with white-light emission from ohmic electrode edges. It cannot be explained by the previous space-charge-limited current model. A new model is proposed in which filling of states near the surface produces an intense electric field near the anode edge and triggers an avalanche.
A new slow-wave coplanar waveguide on a semi-insulating GaAs substrate is described. The waveguide utilises a novel `cross-tie? periodic structure, consisting of lossless media. A simple analysis and experiments show linear dispersion with 10 to 40 times reduction of wavelength. The line appears useful for miniaturisation of distributed circuits in GaAs monolithic microwave integrated circuits.
