A crystal is a solid with a periodic atomic structure and a deviation from the periodicity of the crystal lattice is called a defect. Crystalline defects include point defects (e.g. colour centres ...

Scientists at the University of Twente have developed a way to create highly ordered semiconductor material at room ...

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 ...

"We did some promising calculations, notably finding that larger structures respond more to ... Clark et al, Optically Defined Phononic Crystal Defect, Physical Review Letters (2024).

which contain information about the local crystal structure, symmetry, and strain. CBED is highly sensitive to small changes in the atomic arrangement and is often used for precise lattice parameter ...

His research interests center on determining the structure and electro-optic ... phase transitions of freely-suspended liquid crystal films, including the interactions and ordering behavior of ...

The team focused on metal halide perovskites, known for their ability to absorb sunlight efficiently and their use in devices ...
