1. Schottky Capacitance The Schottky junction can be used as a voltage tuned capacitance in an integrated circuit. (a) Make a plot of capacitance per unit area as a function of voltage for a Schottky capacitor formed from an Ag contact on n silicon doped to Nd = 1 x 1018 /cm? (b) Make a plot of the capacitance per unit area as a function of doping for a Schottky capacitor formed from an Ag contact on n silicon at zero applied voltage. (c) Describe in detail how would you design a Schottky capacitor for maximum voltage sensitivity. Your design choices should include metals (Ag, Al, Au, Cr, Ni, Pt and W) and semiconductors (silicon and GaAs) as well as doping. (d) Describe in detail how would you design a Schottky capacitor for maximum voltage range. Your design choices should include metals (Ag, Al, Au, Cr, Ni, Pt and W) and semiconductors (silicon and GaAs) as well as doping. 1.
