Hole density dependence of q and Γ. (a) Hole density (doping density) against 1,000 × q-1·q-1 is proportional to the hole density. The doping element (aluminum and boron) has no significant effect on the calibration. (b) Hole density (doping density) against line width Γ. The fit shows a quadratic dependence of Γ on the hole density.
