Scientists have discovered the mechanism involved when transition metal dichalcogenides on metallic substrates transform from the semiconducting 1H-phase to the quasi-metallic 1T'-phase.

Two-dimensional (2D) semiconductors have emerged as a material platform for the investigation of exciton physics. Their reduced dimensionality, combined with weak screening, fosters robust Coulomb ...

In 1951, physicist Julian Schwinger theorized that by applying a uniform electrical field to a vacuum, electron-positron ...

New experiments using one-dimensional gases of ultra-cold atoms reveal a universality in how quantum systems composed of many particles change over time following a large influx of energy that throws ...

The standard model of particle physics represents the most comprehensive theory about fundamental or subatomic particles and forces in the universe. The model describes how matter and antimatter ...

Why do we live in a universe with three dimensions of space and one of time—3+1 dimensions, as cosmologists would say? Why not some other combination, such as four dimensions of space or two ...

The new solar cell is a lead-free low-dimensional perovskite material with a superlattice crystal structure—a first in the field. What’s special about this material is that it exhibits efficient ...
