MODELING OF PARABOLIC QUANTUM-WELL WIRE CHANNELS FOR MODULATION-DOPED FIELD-EFFECT TRANSISTORS

A two-dimensional approach, used in the analysis of optical modes of stripe-geometry lasers, is adapted in a novel way for evaluating the parameters of parabolic quantum well wire (PQWW) structures. Electron wave functions and energy levels are computed by finding the electronic analog of the optical parameters. The concentration of one-dimensional electron gas (IDEG) is computed by solving Schrödinger’s and Poissons’ equations self-consistently. A charge control model is developed to evaluate the current-voltage and transconductance characteristics of the proposed 1-D MODFETs having parabolic quantum well wire channels. © 1993 Academic Press.
