  • Low dimensional complex oxides

Complex oxides exhibit variety of structures, electric and magnetic transitions with change of conditions like temperature, pressure, doping, and external fields. Their properties, such as electron transport, dielectrics, magnetism, which can be resorted to the strong coupling between spin, charge, orbital, lattice and etc., have long been scientifically interesting and proven commercially useful. The endeavor at developing new advanced materials and tuning known materials to realize novel and multiple functionalities (e.g. information storage and processing, energy conversion and storage), strong coupling between different properties and tunabilities has been a focus for studying complex oxides. Taking advantage of many emerging phenomena at nanoscale has become a fruitful way of tailoring the properties of complex oxides. In addition, the effort on the integration of complex oxides into heterostructures and the interfaces with other functional materials is becoming more and more a focus. Here we are particularly interested in the interface between low dimensional complex oxides and organic semiconductors.


  • Interface between complex oxides and organic semiconductors

Organic semiconductors hold great potential in energy related applications such as organic light-emitting diode and organic photovoltaics. These organic electronics are highly attractive because of their light weight, flexibility, and environmental friendliness. The interfacial properties between organic semiconductors and the inorganic materials are among the intrinsic factors governing the device performance (e.g. energy conversion efficiency), stability (life time) and predictability. In particular, the possible tunability of the organic semiconductor devices offered by the interface between organic semiconductors and tunable complex oxides is extremely intriguing.
