The |medea| *Deposition* module facilitates the simulations of automated, continuous impact of pre-defined particles on to a surface and enables you to examine the dynamical processes and mechanisms that govern particle-surface reactions and interactions. **Key Benefits** * Deposition of any amount of various particle types such as atoms, cluster, and molecules * Impact the surface with user-defined particle velocities or energies, angles, and frequencies * Study the effects of deposition parameters on surface morphology and atomic distribution * Automated analysis of results such as particle distribution plots Computational Characteristics ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ * Users define impact region, impact velocity/energy, impact angle, impact frequency, and total number of deposits per deposition particle type .. image:: /Datasheets/images/deposition_1.png :align: center :width: 3.0in * |medea| |deposition| uses the LAMMPS classical molecular dynamics engine for efficient performance on computers from scalar workstations to massively parallel supercomputers * Temperature control of the substrate with the Langevin thermostat * Creates distribution plots automatically per deposition particle type for analyses of penetration depth, reaction range, growth thickness, etc. .. image:: /Datasheets/images/deposition_2.png :align: center :width: 3.0in * Works with reactive forcefields such as MLP, ReaxFF, COMB3, Tersoff, and EAM, as well as non-reactive valence forcefields such as PCFF+ Required Modules ^^^^^^^^^^^^^^^^ * |medea| |menvironment| * |medea| |deposition| Recommended Modules ^^^^^^^^^^^^^^^^^^^ * |medea| |mlp| * |medea| |reaxff| * |medea| |comb3| Find Out More ^^^^^^^^^^^^^ Contact Materials Design to see how |medea| |deposition| can be employed in the following tutorials: * Deposition of |O2| on Si Surface with reactive forcefields .. only:: html :download: :download:`pdf `
