摘要：
Magnetotransport phenomena in unidirectional lateral superlattice (LSL) systems of short and ultrashort periods have been studied. Commensurability oscillation is observed in the composite fermion regeme near V=3/2. Quenching of the spin gap at odd integer filling by the potential modulation is demonstrated. Reproducible magnetoresistance fluctuation has been found in one of the ultrashort LSL samples.
