class Process(structure, equation_values, timings, deposition_scaling=1, temp_tracking=True, name=None)[source]#

Bases: object

Class representing the core deposition process. It contains all necessary arrays, variables, parameters and methods to construct a continuous deposition process.

Methods

`check_cells_filled`	Check if any deposit cells are fully filled
`deposition`	Calculate an increment of a deposited volume for all irradiated cells over a time step
`diffusion_coefficient`	Calculate surface diffusion coefficient for every surface cell.
`diffusion_coefficient_expression`	Calculate surface diffusion coefficient at a specified temperature.
`equilibrate`	Bring precursor coverage to a steady state with a given accuracy
`get_dt`
`heat_transfer`	Define heating effect on the process
`precursor_density`	Calculate an increment of the precursor density for every surface cell
`residence_time`	Calculate residence time for every surface cell.
`residence_time_expression`	Calculate residence time at the given temperature :type temp: :param temp: temperature, K :return:
`update_helper_arrays`	Define new views to data arrays, create axillary indexes and flatten beam_matrix array
`update_surface`	Updates all data arrays after a cell is filled.

Returns:: bool

deposition()[source]#

Calculate an increment of a deposited volume for all irradiated cells over a time step

Returns:

diffusion_coefficient()[source]#

Calculate surface diffusion coefficient for every surface cell.

Returns:

diffusion_coefficient_expression(temp=294)[source]#

Parameters:: eps – desired accuracy

heat_transfer(heating)[source]#

Define heating effect on the process

Parameters:: heating – volumetric heat sources distribution
Returns:

property nd#
