Monolayer-Defined Flat Colloidal PbSe Quantum Dots in Extreme Confinement

Leon Biesterfeld, Huu Thoai Ngo, Ahmed Addad, Dominik Rudolph, Wolfgang Leis, Michael Seitz, Gang Ji, Bruno Grandidier, Christophe Delerue, Jannika Lauth, Louis Biadala

Colloidal 2D PbX (X = S, Se, Te) nanocrystals are innovative materials pushing the boundaries of quantum confinement by combining crystal thicknesses down to a monolayer with additional confinement in the lateral dimension. These flat PbSe quantum dots (fQDs) exhibit telecommunication band…

Simultaneous Photonic And Phononic Topological Interface States In A Si-based Membrane Crystal

Nouh Krai, Gaëtan Lévêque, Bahram Djafari-Rouhani, Yan Pennec

We investigate the emergence of topological interface states in a silicon-based crystal supporting both photonic and phononic modes. Our results demonstrate that these modes are robust and immune to certain defects, such as bends, ensuring stable wave propagation.

Spectral Frequency Response of Hypersonic Phonons in a Non-Trivial Topological Waveguide

O.R. Ranjbar-Naeini, O. Florez, M.D. Koijam, B. Djafari Rouhani, Y. Pennec, T. Makkonen, O.M.E. Ylivaara, Sara Pourjamal, J. Ahopelto, C.M Sotomayor Torres

The spectral frequency response of a hypersonic phononic wave propagating along a non-trivial topological waveguide is obtained by laser Doppler vibrometry. The guided mode at 2.115 GHz is shown to propagate with minimal loss.
