[Effect of electric field on exciton energy level width in quantum well].
By using concept as quasi-classical particles, the particles which move in a large range of space in solid state are described. Applying the derived formula of energy uncertainty and exciton model of classical mechanics to GaAs/GaAIAs quantum well in electric field, the calculation results of exciton energy level width arc in agreement with measured results. The great different effects of perpendicular-field and parallel-field on exciton optical absorption in the quantum well can be explained clearly and simply.
