An algorithm for simulating animal evolution has been adapted to predict a silicon-based material fit for optoelectronics applications.

Bundles of nearly identical carbon nanotubes have properties that are well-suited for making electricity from light.

Theorists propose an experiment to observe a “phoniton,” a novel hybrid of an electron and a quantum of vibration in a crystal lattice.

Light emitting diodes with superconducting electrodes are better photon emitters.

In a superconductor-semiconductor hybrid system, circularly polarized light can generate an electric current without the system leaving thermal equilibrium.

Electric-field control of the spin-orbit field in [111] quantum wells lengthens the spin coherence time.

Researchers predict that Majorana fermions can be found in magnetic field vortices in the bulk of the superconductor Cu_{x}Bi_{2}Se_{3}.
