Experimental Realization of a Reconfigurable Electroacoustic Topological Insulator

Amir Darabi, Manuel Collet, Michael J Leamy

A substantial challenge in guiding elastic waves is the presence of reflection and scattering at sharp edges, defects, and disorders. Recently, mechanical topological insulators ha…

Numerical optimization of a prestressed auxetic metamaterial for vibration isolation

Adrien Pyskir, Manuel Collet, Zoran Dimitrijevic +1

We present a numerical study on an enhanced periodic auxetic metamaterial. Rotating squares mechanism allied to precompression induced buckling give these elastic structures exotic…

Enhanced ferroelectricity in epitaxial Hf0.5Zr0.5O2 thin films integrated with Si(001) using SrTiO3 templates

J. Lyu, I. Fina, R. Bachelet +5

SrTiO3 templates have been used to integrate epitaxial bilayers of ferroelectric Hf0.5Zr0.5O2 and La2/3Sr1/3MnO3 bottom electrode on Si(001). The Hf0.5Zr0.5O2 films show enhanced p…
