A team of researchers has discovered an effective method for removing lattice defects from crystals. A team of researchers from Osaka University, the Institute for High Pressure Physics and the ...

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 ...

PROVIDENCE, R.I. [Brown University] -- In 1972, physicists J. Michael Kosterlitz and David Thouless published a groundbreaking theory of how phase changes could occur in two-dimensional materials.

Perovskite solar cells have been the subject of much research as the next generation of photovoltaic devices. However, many challenges remain to be overcome for the practical application. One of them ...

Charge localization (trapping) phenomena in semiconducting and insulating crystalline solids are central to the function of all present and future electronic devices. A free charge carrier injected ...
