König and colleagues: quantum spin Hall state in HgTe wells

What changed

A predicted 2D topological phase gained material-system experimental evidence.

Scientific scope

Exact eight-author 2007 paper; prior theory, 3D topological insulators and later devices excluded.

Evidence

The linked sources identify this contribution and its scope. WRS has not independently reconstructed the scientific claims. The record is the exact 2007 Science paper. Kane–Mele theory, the HgTe material prediction, later three-dimensional topological insulators and subsequent device studies remain separately attributable.
