Gamma{ }

Calling sequence

classical{ Gamma{ } }

Properties

• usage: \(\mathrm{\textcolor{Dandelion}{conditional}}\)

• items: \(\mathrm{maximum\;1}\)

Dependencies

• At least one of the following: Gamma{ }, X{ }, Delta{ }, and L{ } is required if global{ crystal_zb{ } } is present in the input file.

• The Gamma{ } is required if global{ crystal_wz{ } } is present in the input file.

Functionality

By calling this group, a conduction band with a minimum at \(\Gamma\) point becomes available in the model. This band is referred to as Gamma in output files.

Example

classical{
    Gamma{}
    HH{}
}

Nested keywords

output_bandedge{ }

Calling sequence

classical{ Gamma{ output_bandedge{ } } }

Properties

• usage: \(\mathrm{\textcolor{ForestGreen}{optional\;within\;the\;group}}\)

• items: \(\mathrm{maximum\;1}\)

Functionality

Output minimum (band edge) of this band as energy profile in a single file [eV].

Example

classical{
    Gamma{
        output_bandedge{}
    }
    HH{}
}

output_bandedge{ averaged }

Calling sequence

classical{ Gamma{ output_bandedge{ averaged } } }

Properties

• usage: \(\mathrm{\textcolor{ForestGreen}{optional\;within\;the\;group}}\)

• type: \(\mathrm{choice}\)

• choices: yes; no

• default: no

Functionality

If set to yes then, for each grid point, the energy profile will be averaged between neighboring material grid points. If set to no then abrupt discontinuities at interfaces are visible in the output files (in 1D two points, in 2D four points, in 3D eight points for each grid point).

Example

classical{
    Gamma{
        output_bandedge{
            averaged = yes
        }
    }
    HH{}
}
