碳结构的强度来源于碳原子(想想金刚石)间强大的化学键。
The strength comes from the powerful chemical bonds that form between carbon atoms (think diamond).
可见,新金刚石是由FCC碳向金刚石结构过渡的中间态结构。
Therefore, we suggest that n-diamond is indeed an intermediate state between the FCC structure and diamond structure.
电子能带结构计算表明sc - C20为宽带隙(4.20 eV)半导体型碳,并且随着压力升高带隙呈现增大的趋势,sc - C20带隙的大小及变化规律与金刚石相似。
Electronic band structure calculations show that sc-C20 is a semiconductor with wide band gap of 4.20 eV, and the gap increase with pressure, similar to that of diamond.
