Trivia Quiz On Semiconductor Material In Science

Let’s start the quiz

A semiconductor material is one whose electrical properties lie between conductors and conductors. Germanium and silicon are the most well-known examples of these substances. It acts as an electron and charge carrier. Thus by adding impurities to pure germanium, the number of free electrons increases i.e. the conductivity of the crystal increases. Out of the five valence electrons of the non-atom, 4 electrons form covalent bonds with one valence electron each of the four atoms of germanium. The 5th valence electron separates from the atom of the impervious and begins to move freely within the crystal. Let's know more about Semiconductor Material In Physics.
