Quantum waves in zinc

The effect of quantization of charge carriers in a magnetic field on the wave properties of zinc is investigated theoretically. It is shown that the cyclotron absorption by holes in the microwave range acquires a clearly manifested quantum structure: the absorption as a function of the magnetic field has the form of a sequence of narrow quantum peaks separated by deep minima. The suppression of cyclotron absorption at the minima is so strong that the propagation of an electron doppleron—the mode characterized by strong damping under classical conditions and not observed in zinc—becomes possible.
