$useschrodn

$useschrodn is very similar to $outputwave. The difference is that $useschrodn will solve Poisson-1D Schrodnger self-consistenly. However, it is hard to get this condition well converged. Therefore, this function is no longer maintained!!

$useschrodn
N_grid Y_top Y_depth Y_interface(Y_int) 

Although 2D solver is based on FEM, when the cross section solver is called, the program solve this problem using FD scheme. Therefore, we need to define Y_top and Y_depth as we used in 1D-DDCC Schrodinger solver to solve this problem. We also need to set N_grid to decide the dy in the FD Schrodinger solver solver. Y_int is for solver to know where is oxide insulator and semiconductor interface. However, this input is no longer used. Therefore, the user can put any value, which will not affect the output.

Note that this command is similar to $useschrodn. The difference is that $useschrodn will solve Poisson+1D Schrondiger (all sections) self-consistently. $outputwave will only output wave function at the end of each bias.
