Source sentences:
text: This effect may be observed in heavily doped semiconductors containing impurities in such high concentrations N im that the mean distance between the impurities, which is proportional to N im 1/3, becomes less than or of the order of the mean distance a separating the impurity from the electron or hole captured by it.
