Abstract

The intrinsic mechanical properties of rubrene single crystals are investigated. The in-plane elastic constants are obtained by inducing the wrinkling instability in crystals laminated on elastomeric substrates. The results demonstrate a dependence of wrinkling wavelength on crystallographic direction. The observed elastic anisotropy suggests a non-linear coupling between mechanical and electrical properties.
