Electron scattering occurs when electrons are deviated from their original trajectory. This is due to the electrostatic forces within matter interaction or, if an external magnetic field is present, the electron may be deflected by the Lorentz force. This scattering typically happens with solids such as metals, semiconductors and insulators; and is a limiting factor in integrated circuits and transistors. Electrons may be scattered through a solid in several ways:

  • Die Elektronenstreuung (in manchen Zusammenhängen auch Elektronenstoß genannt) ist eine verbreitete Untersuchungsmethode speziell in der Atom- und Kernphysik. Hierbei werden Elektronen an dem Coulombpotential des Atoms gestreut, zudem wechselwirken die Spins von Elektron und Kern miteinander. Aus der Analyse der gestreuten Elektronen erhält man den Formfaktor der Ladungsverteilung, was der Fouriertransformierten der Ladungsverteilung entspricht. Man unterscheidet zwischen elastischer und inelastischer Streuung. Der differentielle Wirkungsquerschnitt beträgt: (de)

  • Lo scattering di elettroni è un processo tramite il quale un elettrone è deflesso dalla sua traiettoria originaria. Gli elettroni sono particelle cariche che risentono della forza elettromagnetica. Essi subiscono scattering da parte di altre particelle cariche interagendo attraverso forze elettrostatiche di Coulomb. Inoltre, se è presente un campo magnetico, un elettrone in movimento sarà deflesso dalla forza di Lorentz. Una descrizione estremamente accurata dello scattering elettronico, che include aspetti quantistica e relativistici, è data dalla elettrodinamica quantistica. (it)
