Overview

Electronic structure analysis indicates tunable band gaps in 2D CuPX monolayers, suggesting potential for optoelectronic devices and flexible electronics.

Key Points

  • Tunable band gaps ranging from 0.03 to 1.97 eV highlight potential applications in optoelectronic devices.
  • The study employed density functional theory to ascertain stability across six structural phases of CuPX monolayers.
  • CuPX monolayers exhibit auxetic materials behavior with negative Poisson's ratios, balancing flexibility and robustness.
  • Biaxial strain application enhances band gap modulation, indicating versatile electronic properties for flexible electronics.
