Quantized Hall resistance: a precise electrical reference

Contribution grade

Physics · Scoped scientific or research-capability contribution

Reference score110,000Provisional editorial estimate of this exact contribution; its grade is assessed separately.

What changed

Measured reproducible Hall-resistance plateaus in a two-dimensional electron system, linking a material measurement to fundamental constants.

Scientific scope

Measured reproducible Hall-resistance plateaus in a two-dimensional electron system, linking a material measurement to fundamental constants. Scope limitation: The integer effect differs from the later fractional effect. The initial experiment is not the complete history of electrical metrology.

Evidence

Assessment uses the catalogue-linked source evidence for the stated contribution. The integer effect differs from the later fractional effect. The initial experiment is not the complete history of electrical metrology.
