文摘

Unconventional behavior of electron transport in a 1D disordered ring is reported. Interplay between Rashba So interaction and disorder is discussed. Disordered ring provides much higher current compared to a perfect one. Results are independent with disorderness, be it correlated or random. MI transition and selective switching effects are discussed.
