Reference score105,000Provisional editorial estimate of this exact contribution; its grade is assessed separately.

What changed

Observed a Hall plateau at one-third Landau-level filling in a high-mobility two-dimensional electron system.

Scientific scope

Observed a Hall plateau at one-third Landau-level filling in a high-mobility two-dimensional electron system. Scope limitation: The observation is separate from Laughlin’s later explanatory theory; the original suggested interpretation is not treated as the final account.

Evidence

Assessment uses the catalogue-linked source evidence for the stated contribution. The observation is separate from Laughlin’s later explanatory theory; the original suggested interpretation is not treated as the final account.
