摘要：

The authors report the breakdown of the nearly dissipationless quantum Hall effect into a set of distinct, quantised dissipative states in a wide, high-quality GaAs/AlGaAs sample. They found 35 dissipative stages on one plateau and nine on another plateau which have longitudinal voltage drops accurately quantised in units of h(cross) omega c/e to within our +or-0.6% measurement uncertainty. This voltage quantisation implies that the energy dissipation per carrier is quantised in units of the Landau level spacing h(cross) omega c.
