Narrow band gap and photon-trapping structures of hexagonal silicon nanowire films were adopted for the photodetector (PD). To obtain higher carrier mobility and longer cutoff wavelengths, strain-engineering-induced wrinkled surface structures were utilized to overcome the band gap limitation and improve photoabsorption. The PDs were flexible, lightweight, tailorable, scalable, and semitransparent. Moreover, they could withstand 33% of tensile strain without structural damage, and the light resistor presents high sensitivity to tensile force and could be used as an optical force sensor. In the unstretched state, the

A promising flexible photodetector based on hybrid nanocomposites of 2D MXene and In2O3 nanoparticles (NPs) has been developed, demonstrating excellent ultraviolet (UV) light responsivity. In this work, In2O3‐decorated MXene nanosheets (In2O3MX) are synthesized via a simple one‐step sonochemical method using ultrasonication, rapidly producing the composites in a short time. The synthesized material shows efficacy across broadband wavelengths (UV, Vis, NIR). Notably, the photodetector using In2O3MX exhibits a responsivity (R) of 121.6 A W−1 and a specific detectivity (D*) of 106.4 × 10¹⁰ Jones in the UV range, and confirming enhanced electrical properties and the feasibility of low‐voltage detection with tau plots. Additionally, the electrical and optical characteristics remain unchanged after bending the device up to 10,000 times with a bending radius of 6.0 mm, highlighting its suitability for flexible optoelectronic applications. Overall, this study introduces a novel approach to the simple synthesis of 2D MXene nanocomposites and provides valuable insights into the development of flexible photodetectors using these materials.
