Investigation of Chemical Bond Properties and Mssbauer Spectroscopy in YBa2Cu3O7 张思远1,高发明2,李东春2 (1.Changchun Institute of Applied Chemistry Academia Sinica, Changchun 130022, China;2.College of Materials Science and Chemical Engineering, Yanshan University, Qinghuangdao 066004,China) Abstract:Chemical bond properties of YBa2Cu3O7 were studied by using the average band-gap model. The calculated......
nanoribbons’ bond angles and bond lengths and the uniaxial tensile strain along armchair edge was established by the static method. By the tight binding method, the relationship among armchair graphene nanoribbons’s energy band and band gap and strain was calculated. The results show that the application of a small uniaxial strain leads to variation of energy subband spacing, which opens a band gap......
