Quasi-particle properties in a quasi-two-dimensional electron liquid
(Indian Academy of Sciences, 2008)
We consider the quasi-particle properties such as the effective mass and spin susceptibility of quasi-two-dimensional electron systems. The finite quantum well width effects are incorporated into the local-field factors ...
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 ...
