doping{ }¶

Calling sequence

structure{ region{ doping{ } } }

Properties

usage: \(\mathrm{\textcolor{Dandelion}{conditional}}\)
items: \(\mathrm{maximum\;1}\)

Functionality

Assigns dopants defined in the global group impurities{ } with selected concentrations.

Examples

structure{
    region{
        doping{...}
        ...
    }
}
impurities{
    ...
}

Note

See — FREE — Schrödinger-Poisson - A comparison to the tutorial file of Greg Snider’s code as an example of use of gaussian1D{ } and gaussian2D{ } for donors and acceptors.

The Figure 2.5.1 shows a 3D doping profile that is defined inside a 20 nm x 20 nm x 50 nm cube where the 50 nm are the z direction. The doping rate profile is homogeneous with respect to the (x,y) plane, it only varies along the z direction.

The doping rate profile is constant between z = 10 nm and z = 25 nm with a rate of 1 x 1018 \([1/cm^3]\). It has Gaussian shape from z = 25 nm to z = 45 nm (gaussian1D). It is zero between z = 0 nm and z = 10 nm, as well as between z = 45 nm and z = 50 nm.
