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 ...

Quantum engineers have spent years trying to tame the fragility of qubits, only to be thwarted by the tiniest imperfections in the materials they use. Now a new line of research flips that problem on ...

If we are to prevent the impending environmental crisis, it is imperative that we find efficient and sustainable ways to avoid being wasteful. One area with much room for improvement is the recycling ...

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 ...

Point defects (e.g. missing, extra or swapped atoms) in crystalline materials often determine the actual electronic and optical response of a given material. For example, controlled substitutions in ...

Researchers show that Cartan's First Structure Equation links crystal defects to the same mathematical rules governing electric currents and magnetic fields. (Nanowerk News) A fundamental goal of ...

Using two-photon excitation, Japanese scientists have, for the first time, observed the internal defects of semiconductor crystals in three-dimensions. Having studied defects to a depth of 200 µm in ...

The second paper, appearing in the journal Nano Letters and led by graduate student Pooja Reddy, describes a clever method to ...

Quantum technology promises to revolutionize computing, communication, and sensing by using the strange behavior of particles at the atomic level. But turning this promise into real devices requires ...

Insights into atomic-scale defects may enable next-generation thin-film transistors for smartphones, televisions, and flexible electronics. (Nanowerk News) Many displays found in smartphones and ...
