Abstract

We report on results of determination of the electron effective mass and the reduced mass as functions of the electron density (ns) at about 100 mK in perpendicular magnetic fields in the range between 1.5 < rs < 6 by magneto-photoluminescence measurements. We find that the obtained effective masses increase with decrease in ns at ns < 1 × 1011 cm- 2.
