Interpretation:
The type of semiconductor is formed when germanium is doped with arsenic has to be determined.
Concept Introduction:
Semiconductors are the substances that have electrical conductivity between conductors and insulators such as materials of silicon and germanium.
p-type semiconductors are those that have positive charge of holes in large concentration than the electrons. In this, majority carriers are holes and minority carriers are electrons. It is formed by doping trivalent elements that have 3 valence electrons with group 14 elements.
n-type semiconductors are those that have electrons in large concentration than the holes. In this majority carriers are electrons and minority carriers are holes. It is formed by doping pentavalent elements that have 5 valence electrons with group 14 elements.

- 8.96 A business manager wants to provide a wider range of p- and n-type semiconductors as a strategy to enhance sales. You are the lead materials engineer assigned to communicate with this manager. How would you explain why there are more ways to build a p-type semiconductor from silicon than there are ways to build an n-type semiconductor from silicon?arrow_forward8.97 The doping of semiconductors can be done with enough precision to tune the size of the band gap in the material. Generally, in order to have a larger band gap, the dopant should be smaller than the main material. If you are a materials engineer and need a semiconductor that has lower conductivity thin pure silicon, what clement or elements could you use as your dopant? (You do not want either an n- or a p- type material) Explain your reasoning.arrow_forwardA compound of Sn, Cd and P are mixed together to synthesize a semiconductor. The phosphorous atoms reside in the corners and faces of a cube and the Cd and Sn atoms each reside in 1/4 of the tetrahedral holes. Provide the formula for the compound.arrow_forward
