Fabrication is the practice of inventing data or results and recording and/or reporting them in the research record. Both of these schemes are probably among the most serious offenses in scientific research as they challenge the credibility of everyone and everything involved in a research effort.
doping, Altering the electrical conductivity of a semiconductor material, such as silicon, by chemically combining it with foreign elements. It results in an excess of electrons (n-type) or a lack of electrons (p-type) in the silicon. See n-type silicon and silicon.he addition of impurities to a semiconductor to achieve a desired characteristic, as in producing an n-type or p-type material. Also known as semiconductor doping.
