Does Increasing Hole Density in an NPN Transistor Base Decrease Beta?

[snabelpablo]

If we make an NPN transistor and change the base doping level so that we get a higher consentration of holes will β increase or decrease? Why?

I know β=IC/IB. Will more holes in the base make more electrons pass from the emitter to the collector increasing IC and thereby β? Or will IB increase propertionally so that β remains the same? What do you think?

Bump. Urgent!

More hole density in an npn base results in a decrease in beta.
