WitrynaThe impurity band problem in semiconductors is formulated in terms of the Green function, the calculation of which has been carried out by a graphical method. Making use of the hydrogen model for the impurity state, the level density of the impurity band as well as the conductivity are calculated for various concentrations of impurities, the ... WitrynaAs with all semiconductor gases it requires a high level of purity – at least 99.999% - and has a wide range of impurities to be detected. The PlasmaDetek2 and the MultiDetek3 combined with the highly safe continuous monitoring sampling system allows the measurement of GeH4 purity with reduced risk. WitrynaThese kinds of impurities are called acceptors. In the presence of an electric field, the holes move around the field and hole conductivity occurs. Semiconductors with a predominance of hole conductivity over the electronic are called p -type semiconductors (from the word positive). The main charge carriers in p -type semiconductors are holes. cryptoencyclopedie.com
