WitrynaDue to the nature of the equations required to describe the physical behavior of the semiconductor, the charge density for both electrons and holes must be specified explicitly on at least on surface in the system. Generally, this is accomplished by specifying the majority carrier concentration. WitrynaIsoelectronic impurities provide scattering and trapping centers for free carriers and excitons. Intuitively, the impurity traps a carrier (electron or hole) and the latter is then trapped by Coulomb interaction with this complex. A particularly interesting case is that of iodine, which traps a hole from an electron–hole pair, thus leaving ...
