We present a straightforward self-organized growth model within the quenched Edwards-Wilkinson universality class. This model accurately reproduces established roughness and growth exponents, confirming its validity for studying interface dynamics.

Area of Science:

  • Physics
  • Materials Science
  • Surface Science

Background:

  • The Edwards-Wilkinson (EW) equation describes the dynamics of interfaces.
  • Understanding universality classes is crucial for classifying different growth models.
  • Quenched disorder introduces randomness that affects growth dynamics.

Purpose of the Study:

  • Introduce a simple self-organized growth model.
  • Investigate its placement within the quenched Edwards-Wilkinson universality class.
  • Determine the roughness and growth exponents for this model.

Main Methods:

  • Development of a simple self-organized growth model.
  • Analysis of the model's scaling behavior.
  • Comparison with established theoretical and numerical results for the quenched EW equation.

Main Results:

  • The model belongs to the quenched Edwards-Wilkinson universality class.
  • Obtained roughness exponent (alpha) ≈ 1.15 and growth exponent (beta) ≈ 0.89.
  • These exponents align well with previous numerical simulations.

Conclusions:

  • The proposed model is a valid representation within the quenched EW universality class.
  • The obtained exponents are consistent with existing literature.
  • Interface velocity is independent of substrate slope in this model.
