Pogloshchenie Elektromagnitnogo Izlucheniya V Kvantovom Kanale: Teoreticheskoe Issledovanie Opticheskikh Svoystv Vitaliy Karpunin Russian edition

Tsel'yu raboty yavlyaetsya teoreticheskoe issledovanie koeffitsienta pogloshcheniya elektromagnitnogo izlucheniya elektronami kvantovogo kanala. V rabote resheny sleduyushchie zadachi 1. Poluchen koeffitsient pogloshcheniya elektromagnitnogo izlucheniya v kvantovom kanale s parabolicheskim potentsialom konfaynmenta. V kachestve vtorogo uderzhivayushchego potentsiala vybran potentsial "zhestkoy" stenki (pryamougol'naya potentsial'naya yama). Issledovan sluchay poperechnogo, po otnosheniyu k kanalu, magnitnogo polya. Pri rassmotrenii rasseyaniya elektronov na opticheskikh fononakh ispol'zovany DO (deformatsionnyy) i PO (polyarizatsionnyy) mekhanizmy elektron-fononnoy svyazi. 2. Poluchen koeffitsient pogloshcheniya elektromagnitnogo izlucheniya v kvantovom kanale so vtorym uderzhivayushchim potentsialom: del'ta - potentsialom dlya DO i PO mekhanizmov elektron-fononnoy svyazi. 3. Provedeno sravnenie dvukh poluchennykh koeffitsientov dlya PO rasseyaniya, a takzhe dlya DO rasseyaniya. 4. Issledovan dopolnitel'nyy vklad v koeffitsient pogloshcheniya, obuslovlennyy perevorachivayushchim spin vzaimodeystviem elektronov s opticheskim fononami. Rabota interesna studentam, aspirantam, i nauchnym rabotnikam, kotorye zanimayutsya issledovaniyami opticheskikh svoystv nizkorazmernykh sistem.
