The longitudinal effective mass of 2D holes in Ge layers of a Ge-G(1-x
)Si(x) multiquantum well structure was measured by different methods i
ncluding the electrophysical method in strong electric fields, Shubnik
ov-de-Haas oscillations, and cyclotron resonance. A dependence of the
hole effective mass on the hole energy (Fermi levels) is studied. A sc
attering mechanism providing the existence of localized states between
Landau levels is discussed. (C) 1997 Elsevier Science S.A.
