These two commands select the net doping and then plot a contour line along the material junction.

We create a structure with an interesting grid using the commands:

This smooths each region of the mesh.
 
foreach m [ [[materCommand | mater]] ] {
    [[BLTplot | CreateBound]] $Win $m [ [[boundCommand | bound]] $m]
}
FlipY $Win 1
 
This code section outlines each section. The grid can be plotted using a combination of the element command and the CreateLine command.
 
  foreach m [ [[materCommand | mater]] ] {
    [[BLTplot | CreateBound]] $Win $m [ [[elementCommand | element]] $m]
}
 
Each material has its grid added to the plot. After some [[BLTWindow | property editing]], the plot looks like:

Contour and Color Plots

A structure is created with the following set of commands: 


Grid2D
[select.html sel] z=1.0e17 name=Boron store
sel z=1.0e15 name=Arsenic store
[../floops/implant.htm implant] arsenic dose=1.0e15 energy=20
[../floops/strip.html strip] photo=az
[../floops/diffuse.html diffuse] time=5 temp=1100 dry


The plot is created with:

[plot.2d.html plot.2d] bound fill
[select.html sel] z = Boron-Arsenic
[contour.html contour] val = 0.0
[select.html sel] z = log10(abs(Boron-Arsenic))
for {set i 15} {$i <= 20.0} {incr i} {
    [contour.html contour] val = $i
}

This code section will draw the [plot.2d.html outline] of the device and stretch it to fill the plot window. The next line [select.html selects] the doping concentration and [contour.html plot]s a line along the metallurgical junction. Then plot variable is selected to the log base 10 of the absolute doping concentration. A loop from 15 to 20 follows with [contour.html contour] lines being drawn each decade for both p- and n-type doping. The resulting plot:

One-Dimensional Plots

Using the same structure as before, we can perform depth plots through several regions of the device. 


[select.html sel] z=log10(Boron)
[plot.1d.html plot.1d] y=-2.0
[select.html sel] z=log10(Arsenic)
[plot.1d.html plot.1d] y=-2.0 !cle

This code section will draw the boron and arsenic concentrations at the left edge of the device. Both lines are on the same plot:
