pynitride.tests.Li1992_SQW.test_SQW_convergence module¶

Tests Schrodinger equation in a GaAs/AlGaAs square quantum well

Based on Li 1992.

class pynitride.tests.Li1992_SQW.test_SQW_convergence.AlGaAs¶

Represents a parameterized material.

surface_barrier(m)¶

Returns the surface barrier height based on the top boundary of the mesh.

Parameters:: m – the mesh, should be the global mesh so there is a top boundary
