Use a ruler to measure the distance from crest to crest on a simple … Spletidentifications for different-sized quantum dots. Semiconductors rely on electron excitation from the ground state into some excited energy level. The space between the excited and ground states is a characteristic energy band gap. When an electron is excited (ejected from ground state), a corresponding hole (positive charge) is left in the ...
