Query: Radiation-induced resistance oscillations in a 2D hole gas: a
  demonstration of a universal effect   We report on a theoretical insight about the microwave-induced resistance
oscillations and zero resistance states when dealing with p-type semiconductors
and holes instead of electrons. We consider a high-mobility two-dimensional
hole gas hosted in a pure Ge/SiGe quantum well. Similarly to electrons we
obtain radiation-induce resistance oscillations and zero resistance states. We
analytically deduce a universal expression for the irradiated
magnetoresistance, explaining the origin of the minima positions and their
$1/4$ cycle phase shift. The outcome is that these phenomena are universal and
only depend on radiation and cyclotron frequencies. We also study the
possibility of having simultaneously two different carriers driven by
radiation: light and heavy holes. As a result the calculated magnetoresistance
reveals an interference profile due to the different effective masses of the
two types of carriers.
