Silicon - University of Denver
2002/11/30· Silicon, however, has remained by far the most widely used semiconductor because of its unique advantages. Among these are (1) it is elemental, so composition is not a problem; (2) it forms a tough, adhering insulating oxide, SiO 2 , that can be used for isolation and protection; and (3) a large variety of impurity atoms are available for controlling its conduction properties.
