... Leptons (electrons, positrons, muons, taus and neutrinos) are fundamental particles – we have no evidence that they are made up of anything smaller. Hadrons (protons, pions, neutrons, kaons etc.) are not fundamental – they are made up of quarks and antiquarks and the gluons that hold them together. ...

... In band theory, n-type semiconductor impurities are (electron) donors, while p-type semiconductor impurities are (electron) acceptors. The setup is as follows: Impurities add in more levels to the energy bands. Without impurities, one has just a valance band and a conduction band with an energy gap ...

DESY
The Deutsches Elektronen-Synchrotron (english German Electron Synchrotron) commonly referred to by the abbreviation DESY, is a national research center in Germany that operates particle accelerators used to investigate the structure of matter. It conducts a broad spectrum of inter-disciplinary scientific research in three main areas: particle and high energy physics; photon science; and the development, construction and operation of particle accelerators. Its name refers to its first project, an electron synchrotron. DESY is publicly financed by the Federal Republic of Germany, the States of Germany, and the German Research Foundation (DFG). DESY is a member of the Helmholtz Association and operates at sites in Hamburg and Zeuthen.
