GaAs材料摻雜問題 求助。。。。!
|
| GaAs材料中摻硅材料可不可以改變禁帶寬度呢???有沒有軟件可以仿真不同摻雜材料和濃度對(duì)材料禁帶的影響?????????? |

GaAs材料中摻硅材料可不可以改變禁帶寬度呢??? The band gap must be changed by doping Si in GaAs. The gaps of the two materials are different. If the structure is not changed, the gap for your doped material may locate between the GaAs and Si. If the structure is changed, ..... 有沒有軟件可以仿真不同摻雜材料和濃度對(duì)材料禁帶的影響。????????? In fact, every code can solve this problem, e.g., PWSCF, VASP, WIEN2K .. But you must have enough computers (the cell is very large and the symmetry is very low). |
