Abstract = {Magnetotransport coefficients have been measured, at temperatures down to 30 mK, in a single-side p-doped Si0.88Ge0.12 strained quantum well. Odd filling factors dominate the transport, indicating a large g factor, and the coefficients are found to be extremely insensitive to the in-plane component of magnetic field. An effective mass of (0.305$\pm$0.01)m0 was deduced from the temperature dependence. The coefficients are discussed in terms of semiclassical transport theory. At low magnetic fields both longitudinal and Hall coefficients could be well explained in this way, in contrast to the situation in GaAs-based heterostructures. Small deviations from theory at higher fields are attributed to localization and Landau-level mixing effects.},
