... The doped polymer is thus a salt. However, it is not the counter ions, I3– or Na+, but the charges on the polymer that are the mobile charge carriers (see Mechanism of polymer conductivity, below). By applying an electric field perpendicular to the film, the counter ions can be made to diffuse from ...
Effective mass of electron in monolayer graphene: Electron
... The Hall mobility of electrons in the graphene sample increases monotonically with a decreasing temperature from room temperature, begins to level off at about 100 K, and saturates at about 50 K (see Fig. 1). This behavior reflects the 2D character of the electrons in the channel.26 Figure 3 shows a ...

the spin of the electron and its role in spectroscopy

Ionization
Ionization is the process by which an atom or a molecule acquires a negative or positive charge by gaining or losing electrons to form ions, often in conjunction with other chemical changes. Ionization can result from the loss of an electron after collisions with sub atomic particles, collisions with other atoms, molecules and ions, or through the interaction with light. Heterolytic bond cleavage and heterolytic substitution reactions can result in the formation of ion pairs. Ionization can occur through radioactive decay by the internal conversion process, in which an excited nucleus transfers its energy to one of the inner-shell electrons causing it to be ejected.
