qmstart and qmdepth is defining the region to solve the schrodinger equation. since the eigen solver requires a much large memory because it solves all eigen functions and eigenvalues. therefore it is usually not suggested to solve the schrodinger equation in the whole windows. we will only suggest user to solve the schrodinger equation in the mqw regions or mosfet oxide semiconductor interface . the way to use these functions are for example qmstart 200.0 qmdepth 500.0 the qmstart always goes with qmdepth. the unit is a. the example above is the solve the schrodinger equation between 200a - 700a 200 500 700 . if the wave function extends to the computing window it will be removed.
