I.N.Goncharuk, A.V.Ilinskii, O.E.Kvashenkina, E.B.Shadrin, “Elektron-elektronnye korrelyatsii v spektrakh kombinatsionnogo rasseyaniya VO2”, Pokazano, chto v monokristallakh i plenkakh silno korrelirovannogo materiala — dioksida vanadiya — pri termostimulirovannom fazovom perekhode iz nizkotemperaturnoi monoklinnoi v vysokotemperaturnuyu tetragonalnuyu fazu uzkolineichatyi spektr kombinatsionnogo rasseyaniya sveta izoliruyuschei (monoklinnoi) fazy transformiruetsya v shirokopolosnyi spektr, kotoryi soderzhit dva maksimuma pri 500 i 5000 cm-1 s shirinami 400 i 3500 cm-1, sootvetstvenno. Ustanovleno, chto po mere priblizheniya temperatury monoklinnoi fazy k temperature strukturnogo fazovogo perekhoda (340 K) kontur linii fonona myagkoi mody s chastotoi 149 cm-1 simmetrii Ag i kontur linii fonona 201 cm-1 simmetrii Ag priobretayut asimmetrichnuyu formu s antirezonansom tipa Fano, kharakternuyu dlya vzaimodeistviya odinochnogo fononnogo kolebaniya s silno korrelirovannym elektronnym kontinuumom. Pokazano, chto termicheskaya transformatsiya maksimumov v spektrakh kombinatsionnogo rasseyaniya sveta metallicheskoi fazy VO2 nakhoditsya v kolichestvennom soglasii s teoriei kombinatsionnogo rasseyaniya sveta v silno korrelirovannykh materialakh., Fizika i tekhnika poluprovodnikov, 55:1 (2013), 147-156
