Impurities used in a semiconductor
Witryna14 kwi 2024 · During the production of 18F, as a result of the interaction of the beam of protons and secondary neutrons with the structural elements of the target body, many radionuclide impurities are created in the cyclotron. As part of this work, we theoretically predicted which isotopes would be activated in the target tantalum or silver bodies. … WitrynaThe simple model for a hydrogen atom can be used to describe the behaviour of an impurity in a semiconductor. Thus the formula for the ionisation energy of a hydrogen atom, and the radius of the lowest orbit of the electron around the hydrogen nucleus. can be applied in modified form to calculate how an electron or hole will interact with its ...
