## Description

- description: 'The exceptional stiffness of diamond is strongly anisotropic due to
    its crystal structure, yet experimental quantification of Young’s modulus along
    different orientations remains limited. Here, we present a direct measurement
    of elastic anisotropy in microwave plasma chemical vapor deposition (MPCVD) single-crystal
    diamond (SCD) by analyzing the resonance frequencies of cantilevers aligned along
    distinct crystallographic directions. The measured Young’s modulus exhibited a
    minimum value of 1085 ± 21 GPa along the <100> direction and a maximum value of
    1189 ± 22 GPa along the <110> direction. The compliance constants derived from
    the MPCVD-SCD differ substantially from previously reported values for natural
    diamonds and are more consistent with first-principles theoretical values. This
    method enables precise determination of orientation-dependent stiffness, revealing
    significant variation in Young’s modulus across crystallographic axes. These insights
    are critical for the design of diamond-based micro- and nano-mechanical systems
    as well as other high-precision devices, where directional elasticity strongly
    influences performance. '
