Unformatted text preview: 100 micron. Assuming the workfunction for Tungsten is 4.55 eV and Ge sheet resistivity of 10 ohm-cm, solve the following problem: Draw the band-diagram in equilibrium. What is the width of the (one sided) depletion layer? Draw the band-diagram with V EB =0.3 volts, and V CB =-5 V. Find the new depletion with for Base-Emitter and Base-Collector junction. REF. J.
