Current nomination records are confidential for 50 years. An expert recommendation or a market listing does not establish an official nomination.
Contribution
An OLED produces light in organic materials when electrical charges recombine. Phosphorescence and thermally activated delayed fluorescence are routes to use excited states more efficiently. High efficiency alone does not settle lifetime, manufacturing cost or device reliability.
Evidence
Citation Laureates identifies influential research. Recognition is not a prediction of a Nobel winner in a particular year.

A materials theorist who investigates why electric and magnetic order can coexist. Her calculations and conceptual work helped establish multiferroics as a field of materials design.
Quantum anomalous Hall effect
The quantum anomalous Hall effect is quantized transverse electrical transport associated with magnetism and topology, without a large external magnetic field. Its experimental observation in magnetic thin films is distinct from the ordinary Hall effect and from a finished commercial device.

Multiferroic materials
Multiferroics combine more than one type of ordered property, often electric polarization and magnetic order. Coupling between them can make electric control of magnetism possible. Not every multiferroic has equally strong coupling or works under practical device conditions.
