The relative conductivity of a semiconductor device is determined by the amount of impurity "doped" into the device during its manufacture. A silicon diode to be used for a specific purpose requires an average cut-on voltage of 0.60 V, and if this is not achieved, the amount of impurity must be adjusted. A sample of diodes was selected and the cut-on voltage was determined. The accompanying SAS output resulted from a request to test the appropriate hypotheses. [Note: SAS explicitly...

How does temperature affect the band structure and the I-V characteristics of semiconductor devices? How does changing the carrier lifetime affect semiconductor devices? For a GaAs PN junction, imagine that the device is to be used as a photo-diode. What width of intrinsic layer would you want to design the device with if the photons only absorb in the depletion/intrinsic regions? Assume: wavelength = 0.75um.

(type if possible) As you’ve seen, static pressures increase with decreasing velocity. Qualitatively describe how this principle explains how an airplane wing generates lift. How might such an analysis be useful in designing certain types of hydraulic structures where the long-term effects of static pressure differences may cause damage and/or failure of the structure? Such problems can be minimized by proper consideration of the flow properties or by overly strengthening the structures. Which approach is most desirable from the standpoint...
