Our group investigates how nanoscale structural design can be used to tailor the mechanical and elastic properties of two-dimensional (2D) materials. In particular, we have demonstrated that the Young’s modulus of suspended WS₂ membranes can be actively modulated through engineered nanostructures. By precisely measuring the resonant vibrational modes of these ultrathin membranes, we quantitatively extract their elastic constants and intrinsic tension, revealing how nanoscale patterning influences mechanical stiffness and strain distribution. This approach provides new insight into strain engineering and mechanical tunability in 2D materials, opening pathways for applications in flexible nanoelectromechanical systems (NEMS), strain-tunable optoelectronic devices, and quantum transducers.
