Energy-transfer rate in a double-quantum-well system due to Coulomb coupling
We study the energy-transfer rate for electrons in a double-quantum-well structure, where the layers are coupled through screened Coulomb interactions. The energy-transfer rate between the layers (similar to the Coulomb ...
Effective mass enhancement in two-dimensional electron systems: The role of interaction and disorder effects
Recent experiments on two-dimensional (2D) electron systems have found a sharp increase in the effective mass of electrons with decreasing electron density. In an effort to understand this behavior we employ the many-body ...
