Experimental Observation of Geometric Phases in Narrow-Gap Semiconductor Heterostructures
We have studied the electron quantum phase by fabricating low dimensional (d â ¤ 2) mesoscopic interferometers in high-quality narrow-gap semiconductor (NGS) heterostructures. The low effective-mass electrons in NGS heterostructures enable observation of delicate quantum phases; and the strong spin-...
