Kineticheskie Koeffitsienty V Kremnii : Klastery radiatsionnykh defektov

V rabote izlozhen novyy podkhod rascheta kineticheskikh koeffitsientov v kremnii,vyrashchennom razlichnymi metodami,posle oblucheniya bystrymi neyronami reaktora.Yadernye chastitsy naryadu s prostymi defektami obrazuyut klastery defektov,okruzhennye oblastyami prostranstvennogo zaryada.Otsutstvie metoda opredeleniya doli ne provodyashchego ob"ema privelo k potere informativnosti khollovskikh izmereniy.V rabote opisano vzaimodeystvie tochechnykh defektov v oblastyakh prostranstvennogo zaryada s oblastyami vysokoy ikh lokalizatsii.Rassmotreno diffuznoe i dreyfovoe dvizhenie nositeley v provodyashchey matritse obraztsov,chto pozvolilo rasschitat' temperaturnuyu zavisimost' dreyfovykh bar'erov.Opredeleny parametry klasterov defektov/srednestatisticheskiy razmer skopleniya defektov;raspredelenie klasterov defektov po razmeram;polozhenie urovnya Fermi v klastere ot urovnya legirovaniya kremniya/. Rassmotrena modifikatsiya radiatsionnykh defektov fonovymi primesyami/kislorod i uglerod/i dany energeticheskie popravki ikh urovney v zapreshchennoy zone kremniya.Opredeleny urovni divakansii v trekh zaryadovykh sostoyaniyakh i dvukh konfiguratsiyakh.Pokazano,chto klastery defektov mogut sluzhit' tsentrami obrazovaniya sverkhreshetki vakansionnykh por.
