doping
Let an agent explain doping in materials science, relay dopants, methods and applications from semiconductor physics sources, describe nanocrystal doping, and distinguish materials doping from doping in sport, chemical adulteration and drug administration.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain doping in materials science, relay dopants, methods and applications from semiconductor physics sources, describe nanocrystal doping, and distinguish materials doping from doping in sport, chemical adulteration and drug administration.
In materials science, the intentional introduction of small amounts of impurities, dopants, into a semiconductor or other material to change its electrical, optical or magnetic properties, such as adding boron or phosphorus to silicon to make p-type or n-type material for transistors and diodes, or, as a registry alias names, doping semiconductor nanocrystals or quantum dots; doping is fundamental to microelectronics and photovoltaics, and it is a distinct concept from doping in sport, which is the use of banned performance-enhancing substances, and from doping in the sense of adulteration. This entry covers the materials sense.
What it is for: Tuning material properties by adding impurities.
It can be explain the concept; relay dopants and methods; relay applications; distinguish other senses.
Distinguishing features
Intentional impurities
Alters carrier concentration
Basis of transistors
Distinct from sport doping
What it looks like
Not visible; controlled impurity profiles in crystals and films.
Physical character
common silicon dopants: boron, phosphorus, arsenic list
n-type and p-type: electron or hole carriers note
registry parents: manufacturing process, chemical modification note
How it is recognised
Adding impurities to tune material properties
Semiconductor nanocrystal doping
Doping in sport uses banned substances; adulteration degrades a product; drug administration is giving medicines
