Negativedi erential resistanceof a 2 Delectrongas in a 1 Dminiband


We experimentally investigate the miniband transport in a novel kind of superlattice fabricated by the “cleaved edge overgrowth” method. The structure represents a eld e ect transistor, where the channel consists of an MBE-grown superlattice perpendicular to the current ow. By means of the gate the Fermi energy can be adjusted between the bottom of the rst… (More)
