In this work, the effects of crystallization and non-lattice oxygen atoms on the Cu_xO-based memory device are investigated. The 150℃-deposited Cu_xO film possesses a larger amount of non-lattice oxygen atoms than those deposited at the higher temperatures, leading to the formation of AlO_y...
Lattice‐mismatch‐generated dislocation structures and their confinement using superlattices in heteroepitaxial GaAs/InP and InP/GaAs grown by chemical beam epitaxy We report a detailed transmission electron microscopy and x‐ray double‐crystal diffractometry study of the lattice‐mismatch‐induced defect st...
Effect of non-lattice oxygen on ZrO2-based resistive switching memory ZrO2-based resistive switching memory has attracted much attention according to its possible application in the next-generation nonvolatile memory. The Al/... CC Lin,YP Chang,HB Lin,... - 《Nanoscale Research Letters》 被引量...

The electronic structures of the metals and oxygen in perovskite oxides can be significantly changed by varying their geometric structures, such as lattice strain [25,26]. Recently, three-dimensional inverse opal (3DIO) porous metal oxides prepared by template methods have been reported with ...
(details of conversion and selectivity shown in Supplementary Table1). As the H2partial pressure changed from 10 to 50 kPa, therBTXvalue increased accordingly from 0.44 to 0.84 mol molFe−1h−1consistent with the fact that H2is required for the oxygen removal from guaiacol. On the ...

In a perfect crystal all atoms would be on their correct lattice positions in the structure. This situation can only exist at the absolute zero of temperature, 0K. Above 0K defects occur in the structure. These defects may be extended defects such as dislocations . The strength of a materia...
the Cr- and Mn-substituted stoichiometries release/absorb 0.039 and 0.056 mol of lattice oxygen, confirming the reducibility of the Mn and consequent formation of additional oxygen vacancies upon reduction. However, the Cr3+in titanate lattice is less reducible that leads to similar oxygen absor...
6). In contrast, the Li2O reflections shift in the opposite sense due to a lattice contraction as a result of either a declining number of interstitial Li+ and/or reduced grain size42. When the oxygen content x reaches 0.5, the driving force to minimise the O–O interaction, hence the ...
