An organic-inorganic hybrid superlattice with near perfect synergistic integration of organic and inorganic constituents was developed to produce properties vastly superior to those of either moiety alone. The complementary hybrid superlattice is composed of multiple quantum wells of 4-mercaptophenol organic monolayers and amorphous ZnO nanolayers. Within the superlattice, multichannel formation was demonstrated at the organic-inorganic interfaces to produce an excellent-performance field effect transistor exhibiting outstanding field-effect mobility with band-like transport and steep subthreshold swing. Furthermore, mutual stabilizations between organic monolayers and ZnO effectively reduced the performance degradation notorious in exclusively organic and ZnO transistors.
开发了一种有机-无机杂化超晶格，其有机和无机成分实现了近乎完美的协同整合，从而产生了比单独任何一种成分都优越得多的性能。这种互补性杂化超晶格由4-巯基苯酚有机单分子层和非晶ZnO纳米层的多个量子阱组成。在超晶格内部，在有机-无机界面处证明了多通道形成，从而产生了一种高性能场效应晶体管，该晶体管具有带状传输和陡峭亚阈值摆幅，展现出出色的场效应迁移率。此外，有机单分子层和ZnO之间的相互稳定作用有效地减少了在纯有机晶体管和ZnO晶体管中臭名昭著的性能退化。
