摘要：

We observe a magnetic-field-driven transition in the two-dimensional electron system in GaAs/AlxGa1-xAs, from a strongly localized insulating phase at B = 0 to the integer quantum Hall phase that includes a fully developed nu = 1 state. The quantum Hall phase terminates with an additional transition from the nu = 1 state to an insulating phase.
