Measurements of the density-dependent many-body electron mass in 2D GaAs/AlGaAs Heterostructures

Y. -W. Tan, J. Zhu, H. L. Stormer +3

We determine the density-dependent electron mass, m*, in two-dimensional (2D) electron systems of GaAs/AlGaAs heterostructures by performing detailed low-temperature Shubnikov deHa…
