Defect-filled lead-halide perovskites rival silicon solar cells because domain walls inside the material separate and guide charges. Researchers visualized these charge-transport networks using a ...

Silicon carbide crystal model with edge dislocations introduced in places marked in red. A single crystallographic plane is presented at the bottom. The places where ...

Physicists may have earned silicon carbide –– a semiconductor commonly used by the electronics industry –– a role at the center of a new generation of information technologies designed to exploit ...

Defect states refer to electronic energy levels that arise from imperfections or irregularities in the crystal structure of materials, particularly in semiconductors and insulators. These ...

Using hard X-ray photoemission spectroscopy, researchers revealed how oxygen vacancies and structural disorder influence subgap state formation. The figure shows the InGaZnO 4 crystal structure, the ...

Diamonds are famous for carrying heat away faster than almost any other solid, yet new research shows that at the scale of individual atoms they can briefly bottle it up instead. Scientists have now ...

Employing newly developed electron microscopy techniques, researchers have, for the first time, measured the spectra of phonons - quantum mechanical vibrations in a lattice - at individual crystalline ...

With a new mathematical model, a team of biophysicists has revealed fresh insights into how biological tissues are shaped by the active motion of structural imperfections known as "topological defects ...
