Witryna5 kwi 2024 · A simple statistical model of the diffusion of impurity atoms in the crystal lattice of metals has been developed. The relationship between the diffusion flux of atoms and the gradient of their chemical potential is obtained from the basic principles of statistical thermodynamics. In chemistry and materials science, impurities are chemical substances inside a confined amount of liquid, gas, or solid, which differ from the chemical composition of the material or compound. Firstly, a pure chemical should appear thermodynamically in at least one chemical phase and can also be characterized by its one-component-phase diagram. Secondly, practically speaking, a pure chemical should prove to be homogeneous (i.e., will show no change of properties after undergoi… earl rountreeWitrynaThe impurity atoms used to form the p—n junction form well-defined energy levels within the band gap.
