Witryna5 lip 2024 · When a semiconductor is doped with a Group V impurity it is called an n-type material, because it now contains a surplus of n egatively charged electrons not … 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].
