pyro_density

Calling sequence

strain{ pyro_density }

Properties

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

• type: \(\mathrm{choice}\)

• choices: yes; no

• default: yes

Dependencies

• This keyword is allowed only if crystal_wz{ } is defined.

Functionality

Calculate pyroelectric charge density and take it into account while solving the Poisson equation.

If material system is not wurtzite, this flag is ignored. The pyroelectric charge density due to spontaneous polarization applies to wurtzite only. In order to obtain pyroelectric charges, it is not necessary to calculate strain. Pyroelectric charges are only present in wurtzite materials but not in zincblende .

Example

strain{
    pyro_density = no
    pseudomorphic_strain{}
}

global{
    crystal_wz{...}
    ...
}
