What Are the Bandgap Values for GaAs and Si?

[Defennder]

I'm doing a lab report on optical absorption of semiconductors. As such I would like to verify the values of the bandgap Eg which I have calculated through experiment. I tried searching Google but I got a lot of results to technical papers which didn't help at all. I would like to know if anyone here can tell me the bandgap value for both GaAs and Si. Thanks.

Si: http://www.ioffe.rssi.ru/SVA/NSM/Semicond/Si/bandstr.html

GaAs: http://www.ioffe.rssi.ru/SVA/NSM/Semicond/GaAs/bandstr.html

Note that Si does not have a direct band gap, at least for the crystalline Si.
