Title: Two- and three-electron bubbles in Al x Ga 1 - x As / Al 0.24 Ga 0.76 As quantum wells

Abstract

We report on transport signatures of eight distinct bubble phases in the $N=3$ Landau level of an Al$$_x$$Ga$$_{1-x}$$As/Al$$_{0.24}$$Ga$$_{0.76}$$As quantum well with $x=0.0015$. These phases occur near partial filling factors $ν^* ≈ 0.2(0.8)$ and $ν^* ≈ 0.3(0.7)$ and have $M=2$ and $M=3$ electrons (holes) per bubble, respectively. We speculate that a small amount of alloy disorder in our sample helps to distinguish these broken symmetry states in low-temperature transport measurements.
