Spektral'nye kharakteristiki koeffitsienta pogloshcheniya a-Si

V monografii rasschitany spektral'nye kharakteristiki koeffitsienta opticheskogo pogloshcheniya gidrogenizirovannykh amorfnykh poluprovodnikov po metodu priblizheniya Devisa-Motta iz formuly Kubo-Grinvuda. Pokazan sposob razdeleniya integrala nakhodyashchiysya v formule Kubo-Grinvuda v sootvetstvie elektronnykh perekhodov i energii pogloshchennykh fotonov. Vyvedeny spektry koeffitsienta pogloshcheniya, kotorye opredelyayutsya elektronnymi perekhodami s uchastiem lokalizovannykh i nelokalizovannykh elektronnykh sostoyaniy nakhodyashchikhsya v khvostakh razreshennykh zon i v etikh zonakh. Issledovana energiya Urbakha i poluchena spektral'naya kharakteristika, ob"yasnyayushchaya temperaturnyy effekt. Polucheny spektral'nye kharakteristiki koeffitsienta pogloshcheniya dlya elektronnykh perekhodov, gde uchastvuet elektronnye sostoyanie raspolozhennye v oborvannykh svyazyakh (defektakh, legiruyushchikh primeyakh).
