$doping

Setting of doping region for each layer.

Format

$doping
N
L Nd Ea

Parameter explaination

• N : number of contiguous doping region $(\AA )$
• Nd : doping concentration. $N_A(+)or{N}_D(-)$　$(e{V}^{-1/2})$
• Ea : Activation energy. $(meV)$

Example

$doping
3
500.0 1.00e+16 25.0
2000.0 1.00e+17 25.0
2500.0 1.00e+18 25.0 

This setting means region of 0-500A has 1e16 doping concertraion, 500-2000A has 1e17 doping concentraion, 2000-2500A has 1e18 doping concentraion. And their activation energy is 25meV.
