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]. Witryna1 sie 2024 · Accepter Type Impurity in Extrinsic Semiconductor. Impurity is said to be acceptor type or positive type p-type if the impurity is trivalent. Typical acceptor impurities are boron, gallium, indium and aluminum. An acceptor impurity atom is also almost of the same size as Ge (or Si) atom and is dislodges a Ge atom in the crystal …

WitrynaThe available data on solid solubilities of impurity elements in germanium and silicon are summarized in the form of solidus or solvus curves. New solubility data are presented for the lead-germanium, zinc-germanium, indium-germanium, antimony-silicon, gallium-silicon and aluminum-silicon systems. The correlation of the solid … Witryna20 sty 2024 · Several O–H and O–D vibrational lines for complexes that involve impurities that are shallow donors and deep acceptors have been reported recently. The present article compares and contrasts the vibrational properties of complexes that involve shallow donors (OD-Si and OD-Ge) with complexes that involve deep … bitenngyousi
