output_carrier_densities_matgrid{ }

Calling sequence

classical{ output_carrier_densities_matgrid{ } }

Properties

• usage: $\mathrm{optional}$

• items: maximum 1

Functionality

Output electron and hole densities defined on the material grid into files density_electron.dat and density_hole.dat expressed in units dependent on dimensionality of the simulation. These are values entering the drift-diffusion model.

Hint

They typically look better than output_carrier_densities{ } for data presentation.

• In 1D simulation the unit is $1/{\mathrm{cm}}^2$

• In 2D simulation the unit is $1/\mathrm{cm}$

• In 3D simulation the unit is $1$

Example

output_carrier_densities_matgrid{ boxes }

Calling sequence

classical{ output_carrier_densities_matgrid{ boxes } }

Properties

• usage: $\mathrm{optional}$

• type: choice

• values: yes or no

• default: no

Functionality

For each grid point, in 1D two points are printed out to mimic abrupt discontinuities at interfaces (in 2D four points, in 3D eight points)

Example

classical{
    output_carrier_densities_matgrid{
        boxes = yes
    }

    Gamma{}
    HH{}
