Method Detail

getRate

private double getRate(int sourceType,
                       int destinationType,
                       double temperature)

getDepositionRatePerSite

public double getDepositionRatePerSite()

Specified by:

getDepositionRatePerSite in interface IRates

getIslandDensity

public double getIslandDensity(double temperature)

Returns the island density mono layer depending on the temperature. How many islands per area site are generated at current temperature. Usually with higher temperature less islands are created, and thus, island density is lower. And the other way around.

Specified by:

getIslandDensity in interface IRates

Parameters:

temperature - Not implemented yet: temperature in Kelvin.

Returns:

island density

initialiseRates

private void initialiseRates()

initialiseEnergies

private void initialiseEnergies()

Using energies instead of direct rates. I choose prefactor (1e11) and temperature (1273) to fix the diffusion energy closest possible to 0.5 eV based on P. Gaillard, T. Chanier, L. Henrard, P. Moskovkin, S. Lucas. Surface Science, Volumes 637–638, July–August 2015, Pages 11-18, http://dx.doi.org/10.1016/j.susc.2015.02.014.

getEnergy

public double getEnergy(int sourceType,
                        int destinationType)

Specified by:

getEnergy in interface IRates

setDepositionFlux

public void setDepositionFlux(double diffusionMl)

Diffusion Mono Layer (F). Utilised to calculate absorption rate. By default it F=0.000035 ML/s. The perimeter deposition is calculated multiplying F (this) and island density.

Specified by:

setDepositionFlux in interface IRates

Parameters:

diffusionMl - diffusion mono layer (deposition flux)

getRates

public double[] getRates(double temperature)

We don't use the temperature by now.

Specified by:

getRates in interface IRates

Parameters:

temperature -

Returns:

rates[64]
