| Abstract: |
| Understanding the growth mechanism of two-dimensional (2D) materials on curved surfaces is vital to both fundamental and applied study.However,very few reports have been found on describing mechanical behaviors and morphological evolution of 2D materials grown on curved surfaces.In fact,thegrowth of 2D materials on curved surfaces unavoidably incur structural deformations and lattice stress/strains.These will further cause intriguing mechanical phenomena such as slipping,buckling,wrinkling and cracking,which ultimately influence the growth kinetics of materials by coupling to chemical reactions at growth fronts.Different from the growth of 2D materials on a plane surface which is dominated by chemical energies and surface diffusions,the growth on curved surfaces is tied to surface geometries of substrates and mechanical properties of the materials,providing the room to form a rich variety of complex morphologies.By reviewing recent research progress in related fields,we analyze key challenges in simulating the growth of 2D materials on curved surfaces.We then suggest potential routes to addressing the challenges by performing a multiscale study through combining atomistic computations (i.e.molecular dynamics and Monte Carlo simulations) and phenomenological approaches (i. e. phase-field method),so as to reveal the growth mechanism of 2D materials on curved surfaces. |
