Type(NODEMATERIAL) :: material is for saving each node's material variables. There are many material parameters saved in the Type "material"
material%dope(i) ! The doping density of node i (unit cm^-3) material%ea(i) ! The activation energy of node i (unit:eV) material%Eg(i) ! The node's bandgap (unit eV) material%impurity(i) ! The node's impurity or fixed charge density material%charges(i) ! The addition node's fixed charge density. It is similar to impurity material%ep(i) ! The node's dielectric connstant. The unit is cgs unit. So if the dielectric constant is, you need to put
material%polx(i) ! The spontaneous and piezo-electric polarization value along x direction. material%poly(i) ! The spontaneous and piezo-electric polarization value along y direction. material%polz(i) ! The spontaneous and piezo-electric polarization value along z direction. The unit is (
). For example, if the polarization is
, you need to put
material%efmass(1,i) ! Effective mass of electron in parallel direciton (x & y) (unit
) material%efmass(2,i) ! effective mass of electron in perpendicular direction (z) (unit
