证明了由液滴外延形成的定义良好的复杂量子环结构。通过改变Ga液滴结晶温度和改变As通量，制备出GaAs/AlGaAs量子单环和同心量子双环，并观察到双环配合物。讨论了这些量子环配合物的生长机理。(c) 2006年美国物理研究所。
Well-defined complex quantum ring structures formed by droplet epitaxy are demonstrated. By varying the temperature of the crystallizing Ga droplets and changing the As flux, GaAs/AlGaAs quantum single rings and concentric quantum double rings are fabricated, and double-ring complexes are observed. The growth mechanism of these quantum ring complexes is addressed. (c) 2006 American Institute of Physics.
