This page describes how to create materials and add them to the MQW solver simulation.
The MQW solver is mainly suitable for III-V materials with a zincblende crystal structure. Materials to be used by the MQW solver must be Semiconductor type and have the KdotP model enabled under the KdotP tab of the Edit Material Properties window. In addition to the k · p properties, the MQW solver uses the band gap, electron effective mass, and work function from the Electronic Properties tab.
The default Material Database included with the finite element IDE includes a number of binary III-V materials with k · p properties enabled and defined. These materials, and alloys created with them, can be used with the MQW solver. For a list of supported materials in the default database included with the MQW solver, see Material Database in Finite Element IDE.
Other III-V materials with zincblende crystal structure can also be used with MQW solver by defining the required k · p parameters. See Semiconductor Material Model Properties for the required k · p parameters.
Adding Materials to the Simulation
See this page for information on creating new semiconductor materials:
Because the MQW solver only uses Semiconductor type materials, Alloys must be converted to Semiconductors before adding them to the simulation. For information on creating alloy materials, see:
