BiSbTeSe2 behaves just how theory says it should.
New technique could sequence DNA.
Northwestern researchers have designed new types of artificially structured optical materials thanks to an algorithm based on Darwinian evolutionary principles.
Carbon nanotube electrodes improve organic thin-film transistor performance regardless of the film morphology and structure, studies show.
First experimental observation of Cooper pairs in a half-Dirac gas.
New phase map of copper-nickel shows that the material can be either “mixed” or “Janus”.

Researchers get around the mismatch in power requirements between transistor switches and wires by designing a transformer that adjusts the voltage from one to the other.
Whether platinum particles are used in a gas or liquid reaction is also important.
New result may ultimately prove useful for information storage or for making qubits bits for quantum computing, albeit at very low temperatures.
Discovery of "plasmoelectric effect" could lead to new solar cells.
Defects could lead to early device failure, say researchers, but they might also be exploited to make better sensors from the atomically thin carbon sheets.
A quantum dot LED structure that includes an insulating layer to balance charge injections demonstrates greater efficiency and stability.
KAUST researchers have succeeded in stretching rigid, brittle, monocrystalline silicon to up to 10 times its original length.
