Polarons are localized quasiparticles that result from the interaction between fermionic particles and bosonic fields. Specifically, polarons are formed when individual electrons in crystals distort their surrounding atomic ...
(Phys.org)—Researchers have finally answered a question that has eluded scientists for years: when exposed to moderately high pressures, why does graphite turn into hexagonal diamond (also called lonsdaleite) and not the ...
(Phys.org)—Virtually all semiconductors used in today's electronic devices are made of silicon having a cubic crystal structure, as silicon naturally crystallizes in the cubic form. In a new study, researchers have fabricated ...
(PhysOrg.com) -- Ever since it's relatively recent discovery, graphene has generated a great deal of interest. Graphene is extracted from graphite in many cases, and consists of a sheet of carbon atoms bound together in a ...
The electron is the basic unit of electricity, as it carries a single negative charge. This is what we're taught in high school physics, and it is overwhelmingly the case in most materials in nature.

Single-photon emitters are crucial building materials suited for optical quantum technologies. Among them, hexagonal boron nitride is a promising two-dimensional material that retains bright, room-temperature single-photon ...
A team of researchers affiliated with multiple institutions in the Republic of Korea working with a colleague from the University of Cambridge, has developed a way to use chemical-vapor deposition to build five layered single-crystal ...
Physicists sometimes come up with crazy stories that sound like science fiction. Some turn out to be true, like how the curvature of space and time described by Einstein was eventually borne out by astronomical measurements. ...
