✦ Synopsis

We report on results of determination of the electron effective mass and the reduced mass as functions of the electron density ðn s Þ at about 100 mK in perpendicular magnetic fields in the range between 1:5or s o6 by magneto-photoluminescence measurements. We find that the obtained effective masses increase with decrease in n s at n s o1 Â 10 11 cm À2 .
