Hidden Quantum Hall Stripes in Al${}_x$Ga${}_{1-x}$As/Al${}_{0.24}$Ga${}_{0.76}$As Quantum Wells

X. Fu, Yi Huang, Q. Shi +4

We report on transport signatures of hidden quantum Hall stripe (hQHS) phases in high ($N>2$) half-filled Landau levels of Al${}_x$Ga${}_{1-x}$As/Al${}_{0.24}$Ga${}_{0.76}$As quantum w…
