Abstract: | We analyze experimental data in order to evaluate Landau Fermi-liquid parameters. By using row data of recent Shubnikov-de
Haas measurements, we derive, as a function of the electron density n
s, results for the compressibility mass of the charged two-dimensional electron gas. The compressibility mass is nearly equal
to the transport mass even in the density region where the transport mass has the tendency to diverge. We conclude that Landau
Fermi-liquid parameter F
0s (n
s) is nearly independent of electron density and close to zero. This result is derived for silicon (100) and silicon (111)
surfaces. We also obtain the dependence of F
1s (n
s), determining the transport mass, and of F
0a (n
s), determining the spin susceptibility. |
