Dissipationless topological channels for information transfer and quantum metrology

Deliverables

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.

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.
