Schrödinger–Poisson
The Schrödinger–Poisson study step is a special case of the Eigenfrequency study step that is used to model bidirectionally coupled Schrödinger–Poisson systems. It is available with the Semiconductor Module. It is similar to the Eigenvalue study step but has an additional section called Iterations, which determines the behavior of the iterative solver loop for self-consistent modeling of the Schrödinger–Poisson system.
Syntax
model.study(stdname).create(fname, "SchrodingerPoisson");
model.study(stdname).feature(fname).set(pname,value);
Description
Study step.
The following properties are available.
on | off
manual | region | all
Eigenvalue search method; the all method finds all eigenvalues for a full matrix and can only be used for small eigenfrequency problems.
lm | lr | sr | li | si
on | off
on | off
on | off
pout | psteps
Probes to use when probesel=manual.
all | none | manual
tout | tsteps
on | off
Absolute tolerance for termination of the solver loop when method = 
minimization_of_global_variable
.
Relative tolerance for termination of the solver loop when method = 
convergence_of_global_variable
.
init | sol
Reference to study or "zero" for zero solution.

auto | all | first | last | from_list | interp | manual | positive integer
Reference to study or "zero" for zero solution.
See Store in Output for possible options and defaults (this property corresponds to the Output column). Possible values are physics, all, none, or selection.

See setEntry() for information about setting the values for a property that uses a String Map. If you use the set(pname,value) method, you have to provide all alternating property name and property value pairs.
