WebThus, the Bohr radius is the distance in an electron–hole exciton, also called the exciton Bohr radius [4]. Every semiconductor material has a characteristic exciton Bohr radius (Figure 5C, D) in which the quantum confinement effect is realized. This unique confinement property causes the “band” of energies to turn into WebOct 29, 2024 · docx, 17.41 KB.
