Effective mass vs carrier concentration in p-type GaAs - any thoughts?

04 April 2014 1 2K Report

Do you know something (data, publication, book chapter etc) about values of holes effective masses in heavily doped p-type GaAs or maybe a relationship: hole effective masses vs. carrier concentration?

How to define an anisotropic material with asymmetric elastic compliance/stiffness matrix in ANSYS APDL?

I need to model an anisotropic material in which the Poisson's ratio ν_12 ≠ ν_21 and so on. Therefore, the elastic compliance matrix wouldn't be a symmetric one. In ANSYS APDL, for TB,ANEL...
