The use of substances or procedures to improve athletic performance and give an athlete an unfair advantage over other competitors.

doping (pop)

A wafer fabrication process in which exposed areas of silicon are bombarded with chemical impurities to alter the way the silicon conducts electricity in those areas.

The process of introducing small, precisely controlled quantities of specific elements into single crystal semiconductors. The fundamental purpose of doping is to engineer the electrical properties of the semiconductor (e.g. resistively, carrier concentration), as part of the manufacture of solid state devices. Ion implantation is the incumbent pro [..]

 Using chemicals or substances to boost performance - usually refers to the use of substances that have been banned by the UCI.

Doping is the process of deliberately altering a semi-Conductor's Conductivity or crystal structure by introducing a small number of impurity atoms into high-purity Semi-conductor crystals. The r [..]

The process of adding impurity atoms to intrinsic (pure) silicon or germanium to improve the conductivity of the semiconductor material.

systematic addition of impurities into a high-purity material in order to manipulate the material properties such as electrical conductivity

The process of adding impurities to semiconductor crystals to increase the number of free charges that can be moved by an external, applied voltage. Doping produces N-type or P-type material.
