Photoexcitation notation
WebSep 1, 2024 · In the present work, taking semiconductor quantum dots (QDs) as an example, we propose a strategy that uses electron-hole pairs generated by photoexcitation to modify the surface chemistry of QDs to induce interparticle chemical bonding, which we call photoexcitation-induced chemical bonding (PEB). Figure 1A illustrates the design concept. WebThe photoexcitation and photoionization of small water clusters, (H 2O) n; n ¼ 2–3, were studied using various quantum chemical methods and ab initio molecular dynamics (AIMD) simulations.2 The AIMD results based on the complete active-space self-consistent eld (CASSCF) method showed that the photoexcitation and photoionization processes are ...
