Diffusion Barriers Block Defect Occupation on Reduced CeO_{2}(111).
Surface defects are believed to govern the adsorption behavior of reducible oxides. We challenge this perception on the basis of a combined scanning-tunneling-microscopy and density-functional-theory study, addressing the Au adsorption on reduced CeO_{2-x}(111). Despite a clear thermodynamic preference for oxygen vacancies, individual Au atoms were found to bind mostly to regular surface sites....
متن کاملImpact of defect occupation on conduction in amorphous Ge2Sb2Te5
Storage concepts employing the resistance of phase-change memory (PRAM) have matured in recent years. Attempts to model the conduction in the amorphous state of phase-change materials dominating the resistance of PRAM devices commonly invoke a connection to the electronic density-of-states (DoS) of the active material in form of a "distance between trap states s". Here, we point out that s depe...
متن کاملDiffusion Barriers
Diffusion is interesting because it is slow. As a result, many studies of diffusion seek ways to make the process fast and selective. For example, most membrane separations use thin polymer films to recover particular chemicals. Nitrogen is separated from air, and water is purified by ultrafiltration. This is an active and important area of diffusion research. However, in other cases, we may se...
متن کاملDefect-Enhanced Electron Transport through Semiconductor Barriers
It has often been suggested that defects can enhance electron tunneling through barriers. Here, we derive a general expression of the current flowing through semiconductor barriers when induced by the presence of defects, taking into account tunneling and other possible mechanisms. Therefore, we calculate the capture probability of free electrons by defects located in the barrier and the subseq...
متن کاملApoplastic diffusion barriers in Arabidopsis.
During the development of Arabidopsis and other land plants, diffusion barriers are formed in the apoplast of specialized tissues within a variety of plant organs. While the cuticle of the epidermis is the primary diffusion barrier in the shoot, the Casparian strips and suberin lamellae of the endodermis and the periderm represent the diffusion barriers in the root. Different classes of molecul...
