Energy Diagram of Solids  

 

With the Regular Solid tab visible, create 10 potential energy diagrams that have a depth of -300 eV, a width of 0.1 nm, and a separation distance of 0.15 nm. Then, click on the Impurity tab and change the Impurity Concentration from 0 to 1. Notice that one of the regular solid potential energy diagrams has turned green. However, it still represents an atom that is identical to the others because its potential energy diagram is identical. To create an impurity, change the depth to -340 eV. Keep the width at 0.100 nm. The figure below illustrates the resulting potential energy diagram representation of the solid with a single impurity atom.
