39.50. Model: Photons are emitted when an atom undergoes a quantum jump from a higher energy level to a lower energy level. On the other hand, photons are absorbed in a quantum jump from a lower energy level to a higher energy level. Because most of the atoms are in the n = 1 ground state, the only quantum jumps in the absorption spectrum start from the n = 1 state.

The two upper states | 2 〉 and | 3 〉 decay with spontaneous emission to the two lower states | 0 〉 and | 1 〉. A mass of 0.250 kg oscillates on a spring with the force constant 110 N/m. Calculate the ground energy level and the separation between the adjacent energy levels. Express the results in joules and in electron-volts. Are quantum effects important? The energy levels agree with the earlier Bohr model, and agree with experiment within a small fraction of an electron volt. If you look at the hydrogen energy levels at extremely high resolution, you do find evidence of some other small effects on the energy. The 2p level is split into a pair of lines by the spin-orbit effect. Figure 9.2: Energy band and block charge diagrams for a p{type device under °at band, accumulation, depletion and inversion conditions. causes the Si bands to bend up at the oxide interface (see Fig.9.2) so that the Fermi level is closer to the valence-band edge. Thus extra holes accumulate at the semiconductor-oxide
