The nature of the multi-layer improves the performance of almost any device. Organic electrons are greatly influenced by the process of the interface. most common the interfaces of electronic devices are those of semiconductors and metal electrodes. Here, the widely studied interfaces between inorganic materials and metals shall be as follows - Explain first. Therefore, the formation of contact between low-metal and p-type semiconductors with high work functions, in accordance with the Mot short-key rules. Contact with two materials of the ~dai item walk function usually leads to a miscalculation. Until the chemical potential is reached, the charge carrier between the two substances will have a significant impact. I made it happen.
