$useaffinity

The program used the band offset ratio to calculate the energy difference between two material. However, the user can use the affinity command to override the use of band offset ratio

For two different materials,the $\mathrm{\Delta }Ec=offset\times (E{g}_A-E{g}_B)$. It will be changed to 解析失敗 (不明函數 "\ksi"): {\displaystyle \Delta Ec = \ksi_{A}-\ksi_{B}) }
