Understanding Oxide-metal Interfaces

چکیده
One of the most important features of the interface between an oxide and a metal is the sharp change in dielectric constant between the two materials. This suggests that the stabilisation of charges (lattice ions and defect centres) in the non-metal by the polarisation of the metal may contribute strongly to the interfacial adhesion. This effect can be treated in classical electrostatics by the method of images. We present the application of this theory to the adhesion of bulk materials and to the properties of thin films and coatings. The predictions of the continuum theory are compared with atomistic calculations of interfaces. Finally, we consider how, in light of this theory, how interfacial adhesion can be influenced and controlled.

Band alignment at metal/organic and metal/oxide/organic interfaces
Charge injection at metal/organic interfaces dictates the performance, lifetime, and stability of organic electronic devices. We demonstrate that interface dipole theory, originally developed to describe Schottky contacts at metal/semiconductor interfaces, can also accurately describe the injection barriers in real organic electronic devices. It is found that theoretically predicted hole inject...

Cross-sections of a hole-conductor-free CH3NH3PbI3 perovskite solar cell were characterized with Kelvin probe force microscopy. A depletion region width of about 45 nm was determined from the measured potential profiles at the interface between CH3NH3PbI3 and nanocrystalline TiO2, whereas a negligible depletion was measured at the CH3NH3PbI3/Al2O3 interface. A complete solar cell can be realize...

Supported catalysts are widely used in industry and can be optimized by tuning the composition and interface of the metal nanoparticles and oxide supports. Rational design of metal-metal oxide interfaces in nanostructured catalysts is critical to achieve better reaction activities and selectivities. We introduce here a new class of nanocrystal tandem catalysts that have multiple metal-metal oxi...

Oxide interfaces have attracted considerable attention in recent years due to the emerging novel behavior which does not exist in the corresponding bulk parent compounds. This opens possibilities for future applications in oxide based electronics and spintronics devices. Among the different materials combinations, heterostructures containing the two simple band insulators LaAlO3 and SrTiO3 have...

A chemical and magnetic characterization of ferromagnet/antiferromagnet interfaces is essential to understand the microscopic origins of exchange anisotropy and other magnetic phenomena. We have used highresolution L-edge x-ray absorption spectroscopy ~XAS!, which is element specific and sensitive to chemical environment and spin orientation, to investigate the interface of antiferromagnetic ox...
