$useaffinity = $1daffinity 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 \Delta Ec =  offset_{ratio}\times (Eg_{A}-Eg_{B} ) . It will be changed to \Delta Ec =  \chi_{A}-\chi_{B}) Using the affinity can overcome the program where two materials has the same bandgap but different electron affinity.
