This paintings investigates the energy-level alignment of hybrid inorganic/organic structures (HIOS) comprising ZnO because the significant inorganic semiconductor. as well as providing crucial insights, the thesis demonstrates HIOS energy-level alignment tuning inside of an remarkable power variety. (Sub)monolayers of natural molecular donors and acceptors are brought as an interlayer to switch HIOS interface-energy degrees. through learning various HIOS with various houses, the writer derives ordinarily legitimate systematic insights into the basic strategies at paintings. as well as molecular pinning degrees, he identifies adsorption-induced band bending and gap-state density of states as taking part in an important position within the interlayer-modified energy-level alignment, therefore laying the basis for rationally controlling HIOS interface digital homes. The thesis additionally offers quantitative descriptions of many points of the strategies, beginning the door for cutting edge HIOS interfaces and for destiny purposes of ZnO in digital devices.
