Abstract:
We have studied magnetotransport of unidirectional lateral superlattice around half-odd filling of Landau levels. For small enough period a=92 nm, intriguing features are observed around two particular filling factors ν=3/2 and 9/2: positive magnetoresistance and commensurability oscillation of hole-based ν=3/2 composite fermions, and new unknown structures around ν=9/2 which might possibly be related to the theoretically-predicted charge density wave formation at higher Landau levels. With slightly larger period a=115 nm, only incomplete signs of these structures are observed.
