Comparison of modulated impurity-concentration InP transferred electron devices for power generation at frequencies above 130 GHz

摘要

In this paper, InP transferred electron devices of various doping profiles have been theoretically investigated for fundamental- and harmonic-mode operation at frequencies up to 260 GHz. The results are based on an efficient and accurate hydrodynamic simulator, which analyzes the device under both conditions: impressed terminal voltage and realistic load impedances. In comparison with state-of-the-art graded profile diodes, improved performance is demonstrated for modulated impurity-concentration devices for both modes of operation.
