Biaxial strain tuning of the optical properties of single-layer transition metal dichalcogenides

Strain engineering: Tuning the bandgap of 2D materials The bandgap of two-dimensional semiconducting materials can be easily tuned in real time by stretching or compressing them. An international team of researcher led by Dr. Andres Castellanos-Gomez at IMDEA Nanoscience, Spain, studied the optical...
