How to get the semiconductor alloys parameters?

Click For Summary
SUMMARY

This discussion focuses on obtaining the elastic, piezoelectric, and dielectric constants for semiconductor alloys Al0.35Ga0.65As and In0.65Al0.45As. The Ioffe Institute's database is recommended as a primary resource for these parameters, particularly in the semiconductor properties section and the n,k-database. Additionally, users can derive properties for these alloys by linearly interpolating between the known constants of AlAs and GaAs, as well as other relevant materials.

PREREQUISITES
  • Understanding of semiconductor alloy compositions (e.g., Al0.35Ga0.65As, In0.65Al0.45As)
  • Familiarity with elastic, piezoelectric, and dielectric constants
  • Knowledge of linear interpolation techniques in material science
  • Access to the Ioffe Institute's semiconductor properties database
NEXT STEPS
  • Research the Ioffe Institute's semiconductor properties database for specific alloy parameters
  • Study linear interpolation methods for calculating material properties
  • Explore the elastic and piezoelectric constants of AlAs and GaAs for comparative analysis
  • Investigate additional databases or resources for semiconductor material properties
USEFUL FOR

Researchers, materials scientists, and engineers working with semiconductor alloys, particularly those focused on the properties of AlGaAs and InAlAs.

I'm working on some calculations on Al0.35Ga0.65As & In0.65Al0.45As.
Someone can tell me where i can find the elastic/piezoelectric/dielectric constants for these rare alloys?? A database for them exist for us to search??
Thx...

Maybe you can find some info in the database of the Ioffe institute:

http://www.ioffe.ru/SVA/NSM/

The section about properties of semiconductors or the n,k-database should have some data on AlGaAs. Whether there is also info on InAlAs, I am not sure.
 
The properties can be found by linearly interpolating between the two extremes i.e. AlAs and GaAs, same for the other materials.
