Researches on second nearest neighbor for lattice vibration of one - dimensional diatomic chain 一維雙原子鏈晶格振動(dòng)中的次近鄰
The lattice vibrations are called phonons ? they behave just like particles , and their emission and absorption by the electrons generate a weak attractive interaction 晶格的振動(dòng)稱為聲子,它們的行為就像粒子,被電子放射或吸收時(shí)會(huì)產(chǎn)生微弱的吸引力。
The fluorescence intensity of pb became weak when the crystal phase began to form in tha the lattice vibration absorbed the energy induced by the fluorescent transition 隨著體系中晶態(tài)的生成, pb離子進(jìn)入晶格中,由于晶格振動(dòng)所產(chǎn)生的聲子吸收了躍遷回落產(chǎn)生的發(fā)光能量, pb離子的熒光強(qiáng)度明顯下降。
This course examines classical and quantum models of electrons and lattice vibrations in solids , emphasizing physical models for elastic properties , electronic transport , and heat capacity 本課程檢驗(yàn)了固體中的電子以及晶格振動(dòng)的經(jīng)典和量子模型,重點(diǎn)強(qiáng)調(diào)于彈性性質(zhì),電子輸運(yùn)過(guò)程和熱容的物理模型。
