Technology opportunities for topological phononic devices
Topological transport of phonons

Report on the transport of phonons via topologically protected edge and interface states both for few and 100s GHz phonons and a benchmarking of photon emission and transport between edge states and topologically trivial waveguides Progress towards lossless and robust transport will be presented

Synthesis of single-crystal and monolayer magnetic TMDCs

Report on the synthesis and relevant characterizations of 1T TMDCs and on the innovations in the technology to fabricate the devices The report will assess the magnetic response in terms of the type and density of doping and defect concentration

Growth of doped-(Bi,Sb)2Te3 and (Bi,Sb)2Te3/FMI heterostructures

Report on the developments related the growth and characterization (structural, electrical, magnetic). The report will assess the performance in terms of the stability of the ferromagnetic phase and the observed QAHE. It will include the fabrication protocols to reduce the contact resistance.

Topological photonic waveguides

Report on the propagation loss lengths in waveguides with topologically protected photonic modes The advantages of such a system over topologically trivial waveguides will be discussed and key areas for optimization of topological photonic waveguides will be identified

Design of topological waveguides

Layout and report of the designs of topological waveguides for photons, phonons and combination of the two. The report will focus on design features that limit propagation losses, and create hybrid photon-phonon systems, including those where both are topologically protected and where topological photonic waveguides overlap with phononic bandgaps. Layouts for fabrication (dxf files) will be included. These designs will provide input to Task 1.4 in WP1 for device fabrication. The report will also include fabrication details.
