Bandgap renormalization in monolayer MoS_2 on CsPbBr_3 quantum dot via charge transfer at room temperature
Subash Adhikari, Ji-Hee Kim, Bumsub Song +9
Many-body effect and strong Coulomb interaction in monolayer transition metal dichalcogenides lead to shrink the intrinsic bandgap, originating from the renormalization of electric…
Optical orientation and alignment of excitons in ensembles of inorganic perovskite nanocrystals
M. O. Nestoklon, S. V. Goupalov, R. I. Dzhioev +12
We demonstrate the optical orientation and alignment of excitons in a two-dimensional layer of CsPbI perovskite nanocrystals prepared by colloidal synthesis and measure the ani…
Highly Efficient Carrier Multiplication in van der Waals layered Materials
Ji-Hee Kim, Matthew R. Bergren, Jin Cheol Park +8
Carrier multiplication (CM), a photo-physical process to generate multiple electron-hole pairs by exploiting excess energy of free carriers, is explored for efficient photovoltaic…
Integrating quantum-dots and dielectric Mie resonators: a hierarchical metamaterial inheriting the best of both
Antonio Capretti, Arnon Lesage, Tom Gregorkiewicz
Nanoscale dielectric resonators and quantum-confined semiconductors have enabled unprecedented control over light absorption and excited charges, respectively. In this work, we emb…
Energy transfer processes in Er-doped SiO2 sensitized with Si nanocrystals
I. Izeddin, D. Timmerman, T. Gregorkiewicz +4
We present a high-resolution photoluminescence study of Er-doped SiO2 sensitized with Si nanocrystals (Si NCs). Emission bands originating from recombination of excitons confined i…
