Materials used in Electronics

• In terms of their electrical properties, materials can be classified into three groups:

  1.  Conductors;
  2.  Semiconductors;
  3.  Insulators;

• When atoms combine to form a solid, crystalline material, they arrange themselves in a symmetrical pattern;
• The atoms within the crystal structure are held together by covalent bonds, which are created by the interaction of the valence electrons of the atoms;
• Silicon is a crystalline material;
