WitrynaINTRODUCTION ELECTRICALLY active impurity elements in ger- manium are classified as hydrogen-like and deep level impurities. Hydrogen-like impurities, which consist of Li and elements of Columns V and III energy levels introduced by many impurities in Ge. Witrynaof calculations of the dependence between impurity con-centration and the energy-gap width. They used electric measurements in these experiments. In these papers the results of 5 different authors are shown. In regard to Ge, at low temperatures (4.2K), the energy-gap vs. impurity concentration dependence is shown in [3].
