6.2. Germanium is an interesting semiconductor because it has a small band gap (Eg 0.67eV). As a result, it has a higher intrinsic concentration ni than either silicon or GaAs. Do you expect the conductivity of intrinsic germanium to be less than or greater than that of intrinsic silicon? How about compared to GaAs? Explain Why?

Consider a gold-GaAs Schottky diode with a capacitance of 1 pF at -1 V. What is the doping density of the GaAs? Also calculate the depletion layer width at zero bias and the field at the surface of the semiconductor at -10 V bias voltage. The area of the diode is 10-5 cm2. Design a platinum-silicon diode with a capacitance of 1 pF and a maximum electric field less than 104 V/cm at -10 V bias. Provide a possible doping...
