Useful tool at finger tip when I have no access to an excel sheet. Adding more substrates including silicon will be helpful.

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.

・Regular update. ・Adjusted to more machine resolutions with improved display.
III-V Comp. is designed to calculate the compositions and material properties of AlGaInAsP compound semiconductors. It assumes either InP or GaAs as the substrate material for these calculations.
The application displays several key properties including compositions (x, y, z), lattice constant, strain, bandgap, relative energy positions of the conduction and valence bands, and effective masses of electrons and holes.
III-V Comp. employs a direct calculation and visualization methodology. Users input known parameters for AlGaInAsP, and the app computes the remaining unknown properties based on established semiconductor physics principles.
As a calculation tool, III-V Comp. does not have a user progress tracking system. Its function is to provide immediate results for specific material property calculations based on user input.
No, III-V Comp. does not offer any certifications. It is a utility application for calculating semiconductor material properties, not a course or educational program.
III-V Comp. is available for iPhone, iPad, and iPod touch devices. It requires iOS 4.0 or later.
III-V Comp. was last updated on December 5, 2024, with version 3.3. The developer, Takuya Ishikawa, has a history of providing updates for this application.
III-V Comp. is a paid application, available for $2.99. There are no in-app purchases or subscription fees associated with its use.
