Band-gap tailoring of ZnO by means of heavy Al doping
Bo E. Sernelius,Bo E. Sernelius,Karl-Fredrik Berggren,Z.-C. Jin,I. Hamberg,Claes-Göran Granqvist +5 more
TL;DR: Optical band gaps, evaluated from spectrophotometric data, were widened in proportion to the Al doping, and could be quantitatively reconciled with an effective-mass model for n-doped semiconductors, provided the polar character of ZnO was accounted for.
