  • Influence of oval defects on transport properties in high-mobility two-dimensional electron gases 
    Bockhorn, L.; Velieva, A.; Hakim, S.; Wagner, Timo; Rugeramigabo, Eddy P.; Schuh, D.; Reichl, C.; Wegscheider, W.; Haug, Rolf J. (College Park, MD : American Institute of Physics, 2016)
    Rare macroscopic growth defects next to a two-dimensional electron gas influence transport properties and cause a negative magnetoresistance. On the basis of this, we show that the number of oval defects seen on the material ...
  • Interaction-induced huge magnetoresistance in a high mobility two-dimensional electron gas 
    Bockhorn, L.; Gornyi, I.V.; Schuh, D.; Wegscheider, W.; Haug, Rolf J. (College Park, MD : American Institute of Physics, 2013)
    A strong negative magnetoresistance is observed in a high-mobility two-dimensional electron gas in a GaAs/Al0.3Ga0.7As quantum well. We discuss that the negative magnetoresistance consists of a small peak induced by a ...
