Numerous devices to apply tunable uniaxial strain are proposed in the literature, but only few for biaxial strain, often with a trade-off between maximum strain and uniformity, reversibility, and device size. We present a compact device that allows for the controlled application of uniform in-plane biaxial strain, with maximum deformation and uniformity comparable to those found in much larger devices. Its performance and strain uniformity over the sample area are modeled using finite element analysis and demonstrated by measuring the response of exfoliated 2H–MoS<sub>2</sub> to strain by Raman spectroscopy.</p> Dewey 500.2 Swiss National Science Foundation Electron matter in correlated electron systems 182652 CH Projects 33 Département de physique de la matière quantique 131 false 783 Groupe Renner https://doi.org/10.26037/yareta:l7rgbesfffacfdyeamggm6snva Review of scientific instruments 94 1 eb261328-3492-45b2-8219-a4654fe6c4d5 Article (Published version) Public Article-scientifique-from-unpaywall.pdf 5173431 application/pdf CC BY-4.0 Vignette Public Strain Device.png 109039 image/png openAccess Faculté des sciences / Section de physique / Département de physique de la matière quantique
