- A p-type semiconductor joined to an n-type semiconductor ... Pick those that apply. Will not allow current to flow in either direction. Has electron current flowing from the n-type to the p-type material Makes a diode Allows positive current flow from the p-type to the n-type materialarrow_forwardHelli. I only need the last part. Plotting power vs voltage if used as a solar cell and give the definition of fill factor. Tnxarrow_forwardA. Why does the conductivity of a semiconductor and some insulators change with impurity content? Compare this with the behaviour of metallic conductors. B. Discuss the location of the Fermi levels of intrinsic and extrinsic (n-type and p-type) semiconductors in low temperature and high temperature ranges. C. Discuss why the structure of the p-n junction is so important to modern technologies that impact our daily life.arrow_forward
- When a p-and n-type semiconductor are joined at an interface their Fermi energies equilibriate. If we extend this thinking and apply it to an interface between a metal and (p-or n-type) semiconductor to make a metal-semiconductor heterojunction, what will the expected outcome be? Use diagrams and words to explain.arrow_forwardC and D pleasearrow_forwardConsider four of semiconductor samples: solid A is orange, solid B is black, solid C is white, and solid D is yellow. Given their colors, rank these semiconductors in order of increasing band gap. A. B < A < D < c B. B < D < A < C C. C < D < A < B D. C < A < D < Barrow_forward
