研究開始時の研究の概要 |
Nanocrystals (NC) can be designed to emit and absorb light of a specific wavelength (color) very efficiently, thus the can be used in many applications ( displays, touchscreens, solarcells). Moreover, in our work we focus on environmental friendly and nontoxic materials. Nontoxic NCs provide new means for bioimaging (diagnostics) and drug delivery (treatment). While NCs have a huge potential, designe and synthesis is very challenging. Therefore our goal is to combine state-of-the-art experiments, computer simulations and machine learning techniques to enhance the development of novel NCs.

研究実績の概要 |
We study the electronic, optical, magnetic and structural properties of nanoparticles. In particular we investigated the cross-over from bulk to quantum-confined nanoparticles to molecular like structures (https://www.nature.com/articles/s41598-023-31989-8). We could show that our quasi-band structure approach captures these regimes well. We were able to correctly assign "band transitions" in quantum-confined nanoparticles, which allows to, consistent with experimental data, to classify nanoparticles into direct and in-direct semiconductors. Moreover we investigated the structural properties of alloyed nanocrystals for high temperatures and we could show that they remain stable even at high temperatures, which is important for future integration into silicon-based electronics. Similarly surface functionalization remains stable even for long periods under ambient conditions. Still ongoing research studies the ultra-small silicon-tin nanoparticles with core-shell structure.
