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

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...

Could you explain why we see a red-shift of an absorption edge with increasing carrier concentration in p-GaAs?

I mean the graph on http://www.ioffe.ru/SVA/NSM/Semicond/GaAs/optic.html titled "Intrinsic absorption edge at 297 K at different doping levels. p-type doping" . What about the Burstein-Moss effect...

What information can give a temperature dependence of a (direct) band gap?

Is there a possibility to extract any information about doping?

Is it feasible to carry out optical modulation spectroscopy by polarization changes instead of photo-, electro-, thermo-, or piezo-modulation?

Have you ever tried to measure a band gap of semiconductors in such a way?
