One of their samples turned out to be a brilliant blue, named YInMn blue after the component elements yttrium, indium and manganese.
The resulting, extremely thin quantum semiconductors are composed of a single atom layer -- in indenene's case, indium atoms -- and act as topological insulators, conducting electricity virtually without resistance along their edges.
The Dortmund physicists led by Dr. Alex Greilich have now designed a special crystal made of indium gallium arsenide, in which the nuclear spins act as a reservoir for the time crystal.
Achieving high-efficiency green emission has been difficult with traditional hexagonal III-nitride even with increasing the indium content -- a costly element required for green emission -- which leads to higher defect densities and efficiency droop.
The researchers pinpointed indium as an exceptionally promising material for fast-charging batteries.
