Ultrafast charge transfer in 2D heterostructures is tunable via interlayer stacking. This study reveals electronic coupling, not distance, governs charge transfer rates, enabling control for optoelectronics and photovoltaics.

Area of Science:

  • Materials Science
  • Condensed Matter Physics
  • Physical Chemistry

Background:

  • Light-induced charge transfer in 2D heterostructures is crucial for optoelectronics and photovoltaics.
  • The precise mechanisms and quantitative characteristics of charge separation based on interlayer stacking remain unclear.

Purpose of the Study:

  • To systematically investigate the influence of interlayer stacking configurations on ultrafast charge transfer dynamics in MoS2/WS2 bilayers.
  • To elucidate the underlying mechanisms governing charge transfer rates in 2D heterostructures.

Main Methods:

  • Utilized time-dependent density functional theory (TD-DFT) methods.
  • Simulated MoS2/WS2 bilayer systems with systematically varied stacking configurations.

Main Results:

  • Slight variations in interlayer geometry significantly modulated charge transfer times (100 fs to 1 ps).
  • Charge transfer rate is primarily governed by electronic coupling between interlayer states, not interlayer distance.
  • A universal dependence of transfer rate on state-coupling strength was identified.

Conclusions:

  • Interlayer stacking configuration is an effective parameter to control ultrafast charge transfer dynamics in 2D heterostructures.
  • Findings facilitate the rational design of 2D heterostructures for advanced optoelectronic and light-harvesting applications.
