Consider a two-band model for an intrinsic semiconductor. the effective mass for electrons in the conduction band is 1.4 me. the effective mass for holes in the valence band is 0.50 me. at room temperature, the scattering time for electrons is 1.4 x 10-13 s, and the scattering time for holes is 0.5 x 10-13s . the effective mass for electrons in the conduction band is 1.4 me, and the effective mass for holes in the valence band is 0.50 me . the hole and electron densities are each 1x 1017 m-3. what is the electrical conductivity?

Which theory was contradicted by experiments with the photoelectric effect? light spreads out after it passes through a small opening. as soon as light strikes metal, electrons will be ejected. visible light, regardless of color, will cause the ejection of electrons when striking metal. the kinetic energy of ejected electrons depends on the frequency of light that strikes the metal.
