Question

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?

Answer 1

Solution:

Technically- The p-type requires a dopant that produces a hole in the silicon crystal (i.e.aluminum); the n-type requires a dopant that adds an electron to the crystal phosphorous). If one were to consider dopants with atomic radii of various sizesin an effort to have a variety of both types, the issue at hand is that the p-type possibilities are all metals relatively easy to use. The options other than P include As and Sb (both metalloids) and the relatively large Bi.

Numerically-The best way to communicate the product potential is by representing the production efficiency and capability in terms of statistical analysis, by providing the deviation error in production of p-,n-type semiconductor will helps in conveying message to manager in an easy numerical representation. One of the suitable method is of using STDDEV-p type for the analysis.
