- This paper studies the interaction of electrons with dopant atoms in bulk semiconductors. The basic phenomenon is well-known, but previous attempts to describe it theoretically have failed to produce good agreement with experiment. Here, a new, rigorous theoretical model is developed, and experimentally verified, which (a) considers an entire array of impurities rather than a single impurity atom and (b) describes electron-impurity interactions as a transport phenomenon in energy space. This new theoretical capability is significant for design of opto-electronic devices, e.g. terahertz lasers, or qubits based on impurities in semiconductors, complementing research on the EPSRC HyperTerahertz Programme grant (EP/P021859/1).
