Abstract:

THE TRANSFERRED ELECTRON DEVICE IS AN ACTIVE DEVICE CAPABLE OF OPERATION AS A DIPOLE DOMAIN DOMINATED GUNN OSCILLATOR AND AS A CIRCUIT CONTROLLED 94 GHZ GUNN OSCILLATOR. THERE ARE SEVERAL KEY INGREDIENTS FOR DEVICE OPERATION. FIRST, THERE IS THE REQUIREMENT THAT THE SEMICONDUCTOR MATERIAL POSSES A REGION OF NEGATIVE DIFFERENTIAL CONDUCTIVITY. SECOND THERE IS THE ISSUE OF DESIGNING THAT PORTION OF THE DEVICE ASSOCIATED WITH LAUNCHING EITHER A GUNN DIPOLE LAYER OR A GUNN ACCUMULATION LAYER. THESE ARE CRITICAL ISSUES BECAUSE THEY IDENTIFY THE MODE OF OPERATION TO BE EXPECTED, AND THE RELEVANT OUTPUT POWER AND EFFICIENCY. THE DIFFICULTY IN DETERMINING WHERE TO PLACE THE LAUNCHING REGION IS COMPOUNDED WHEN IT IS REALIZED THAT THE DESIGN FEATURES ARE DEPENDENT IN A CRITICAL WAY ON WHETHER THE DEVICE IS CONFIGURED AS, E.G., A PLANAR OR MESA STRUCTURE. THE PURPOSED OF THIS PROPOSAL IS TO DESCRIBE A NUMERICAL PROGRAM FOR THE LAUNCHING OF DIPOLE AND ACCUMULATION LAYERS THROUGH THE PRESENCE OF A HETEROSTRUCTURE LAUNCHER. THE APPLICATIONS ARE TO ALGAAS/GAAS AND INGAAS/GAAS MESA STRUCTURE CONFIGURED DEVICES.
