removeDoping¶

removeDoping(configuration, tag)¶

Remove doping from the tagged atoms of the configuration.

Parameters:

configuration (AtomicConfiguration) – The configuration to affect.
tag (str) – The tag of the doped atoms.

Usage Examples¶

Remove doping on the selection of atoms tagged ‘doping_0’.
