WebDec 16, 2024 · The exciton size and dynamics were studied using time-resolved laser spectroscopy. At early times (~100 fs), the exciton was found to delocalize over similar to ~1–2 molecular units in both assemblies, which reflects the confined nature of excitons in carbon-based materials and is consistent with the calculated value of ~2 molecular units. WebJan 15, 2024 · The broken mirror symmetry of two-dimensional (2D) Janus materials brings novel quantum properties and various application prospects. Particularly, when stacking into heterostructures, their intrinsic dipole moments and large band offsets are very favorable to the photoexcited properties concerning electron–hole pairs, i.e., excitons.However, the … empowhr roles https://cascaderimbengals.com
