Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
III
Calculate material properties for III-V compound semiconductors like AlGaInAsP. It determines compositions, lattice constant, strain, bandgap, and effective masses for InP or GaAs substrates.
- III-V compound semiconductor calculations
- Material property determination
- Composition calculation (x, y, z)
- Lattice constant and strain analysis
- Bandgap and effective mass calculation
- Supports InP and GaAs substrates

Application to calculate the compositions and material properties of a III-V compound semiconductor. Either InP or GaAs is assumed for the substrate. Some of the compositions and material parameters of the AlGaInAsP compound semiconductor are specified to determine the remain unknown parameters. The following properties are shown as a result: compositions (x, y, z), lattice constant, strain, bandgap, relative energy positions of the conduction and valence bands, and effective masses of the electron and holes.
