Organicheskie Provodniki: Lokalizatsiya Nositeley Zaryada V Soedineniyakh Na Osnove Bedt-ttf Alisa Chernen'kaya Russian edition

Issledovaniya v oblasti nizkorazmernykh organicheskikh provodnikov otnosyatsya k nauchnomu napravleniyu, lezhashchemu na styke khimii i fiziki tverdogo tela. Ponizhennaya razmernost' i otnositel'no nizkaya kontsentratsiya nositeley zaryada v kation-radikal'nykh solyakh privodyat k sil'nym elektronnym korrelyatsiyam i poyavleniyu raznogo tipa fazovykh perekhodov. Naibolee obshirnym klassom 2D organicheskikh provodnikov yavlyayutsya kation-radikal'nye soli bis(etilenditio) tetratiaful'valena (BEDT-TTF) i ego analogov. V dannoy rabote privoditsya obzor osnovnykh tipov organicheskikh provodnikov i elektronnykh perekhodov, nablyudaemykh v kation-radikal'nykh solyakh. Rassmatrivayutsya eksperimental'nye metody izucheniya spinovoy dinamiki dyrok: EPR-spektroskopiya i SKVID magnetometriya. Issleduetsya vliyanie lokalizatsii nositeley zaryada i fazovykh perekhodov na spinovuyu dinamiku v kristallakh na osnove (BEDT-TTF). Poluchennye rezul'taty imeyut fundamental'nyy kharakter i mogut byt' poleznymi pri izuchenii protsessov lokalizatsii nositeley zaryada i sil'nykh spin-spinovykh i zaryadovykh korrelyatsiy v usloviyakh ponizhennoy razmernosti.
