HIGHLIGHTS
- who: Cyrine Ernandes from the (UNIVERSITY) have published the article: Indirect to direct band gap crossover in two-dimensional WS2(1−x)Se2x alloys, in the Journal: (JOURNAL)
- what: In Fig 1b, the authors show an optical image of a representative flake, identified from its darker optical contrast with respect to the underlying substrate, exhibiting an equilateral triangle shape.
- how: The results are in agreement with a previous PL study on the WS2(1-x)Se2x alloy28. To unambiguously evaluate the direct or indirect bandgap character of the 1 ML 2 ML and . . .
