Here are the solutions to the questions: 1. a) i) What is a semiconductor? A semiconductor is a material with electrical conductivity between that of a conductor and an insulator. Its conductivity can be significantly altered by temperature or by adding impurities (doping). 1. a) ii) Distinguish between a p-type semiconductor and an n-type semiconductor. p-type semiconductor: Created by doping a pure semiconductor with trivalent impurities (e.g., boron), resulting in a majority of holes* (electron vacancies) as charge carriers. n-type semiconductor: Created by doping a pure semiconductor with pentavalent impurities (e.g., phosphorus), resulting in a majority of free electrons* as charge carriers. **
