TURLI HARORATLARDA UGLEROD NANOTRUBKALARI DASTASINING REZONANS XUSUSIYATLARINI MOLEKULYAR DINAMIKA USULIDA TADQIQ QILISH
##submission.downloads##
Uglerod nanotrubkalari (UNT) yuqori mexanik mustahkamlik, kichik massa va yuqori rezonans xususiyatlari sababli nanoo‘lchamli rezonatorlar hamda sensor tizimlarida keng qo‘llanilmoqda. Nanoo‘lchamli rezonatorlarning asosiy muammolaridan biri termik muhit ta’sirida ularning rezonans chastotalari va dinamik barqarorligining o‘zgarishidir. Ushbu ishda 200 K dan 500 K gacha bo‘lgan harorat intervalida UNT dastasining tebranish xususiyatlari molekulyar dinamika usuli asosida tadqiq qilindi. Turli termik sharoitlarda UNT dastasining amplituda–chastota xarakteristikalari (ACHX) tahlil qilinib, rezonans chastotalari aniqlandi.
