有机分子纳米晶体晶格和表面振动光谱的温度变化(COMPUTER模型)
Temperature Changes of Spectra of the Lattice and Surface Oscillations of Organic Molecular Nano-Crystals (COMPUTER Modeling)
摘要:
研究了有机纳米晶体在结构中存在空位时晶格振荡的频谱与温度的关系。在频谱中,观察到许多随温度单调变化的附加谱线。此外,表面振荡的频谱计算温度变化。同时,低频线随温度变化具有非线性行为。
英文摘要:
Dependence of frequency spectra of the lattice oscillations of organic nano-crystals on temperature is studied at presence of vacancies in structure. In a frequency spectrum a number of additional lines monotonously changing with temperature is observed. Also, the spectrum of the surface oscillations is calculated at temperature change. At the same time, the low-frequency line has non-linear behavior with temperature change.
