Abstract

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