| Summary: | Semiconductor crystals are difficult dynamic systems in which emergence of electric not stability is possible (failure of current, spontaneous fluctuations of current or tension, switching and a hysteresis in volt — the ampere characteristic, etc.). This instability meets in many materials, in different temperature areas and at various levels of excitement. In article instability of some branches of volts — the ampere characteristic of semiconductor devices — existence of the negative differential conductivity (NDC) of S-and N-of types is considered. It is shown that NDC are connected with not stability operated by tension or current. The main electronic mechanisms resulting in negative differential conductivity are considered.
