Overview

Research shows how twist angle alters optoelectronic properties in TMDs, highlighting interlayer coupling's role.

Key Points

  • Higher twist angles promote changes in bandgap transition, leading to direct transitions within the heterostructures.
  • Density functional theory was used to analyze the effects of structural modifications on electronic properties across various stacks.
  • Interlayer coupling variations were observed, particularly weak in structures at specific twist angles like 21.79° and 38.21°.
  • The findings suggest significant implications for applications in optoelectronics and valleytronics, calling for deeper investigation.
