SUMMARY
The discussion clarifies that the notation cm-3 is used to represent atom density in doped silicon crystals, specifically indicating a concentration of 1 x 1018 atoms of antimony per cubic centimeter. This notation is essential for calculating semiconductor operation, as it conveys the number of atoms in a defined volume. The confusion regarding the use of negative exponents is resolved by explaining that cm-3 is equivalent to 1/cm3, emphasizing the concept of density per unit volume.
