$QMdepth

The 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.

Example

$QMstart 
200.0 
$QMdepth 
300.0 

The qmstart always goes with qmdepth. the unit is Å. The example above is the solve the schrodinger equation between 200Å ~ 500Å. If the wave function extends to the computing window it will be removed.

The $QMdepth setting for 1D-DDCC in GUI interface

1.Press the Schrodinger Eigen Solver.
2.Press Enable Schrodinger eigen solver.
3.Adjust to the depth(End-start).
