An electron is confined to a 1 micron layer of GaAs. Assuming that the semiconductor can be adequately described by a one-dimensional quantum well wi th infinite walls, calculate the lowest possible energy within the material in units of electron volt. If the energy is interpreted as the kinetic energy of the electron, what is the corresponding electron velocity? The effective mass of electrons in GaAs is 0.067m0 , where 1 m0=9.10x 10-kg is the free electron rest mass).
