What are the classification of electronic materials?

Here we are going to study the classification of electronic materials. And you can also say difference between conductor, insulator and semiconductor, Then let’s start this topic. Depending on the number of valence electrons, materials are classify in to three types.  Valency < 4  ⇒ Conductor/ metals   Valency  =  4  ⇒  Semiconductor    Valency  > 4 … Read more
