On size effect of cleavage cracking in polycrystalline thin films
A crack trapping model is developed for the fracture resistance of high-angle grain boundaries in free-standing brittle thin films, based on which a new size effect is predicted. In addition to the crystallographic misorientations, the grain boundary toughness is also dependent on the film thickness, primarily due to the geometrically necessary crack front branching. 2007 Elsevier Ltd.

متن کاملPhoton Mapping of MgO thin Films with an STM
The light emission from an STM junction consisting of an MgO thin film on Mo(001) and an Au tip is analyzed with respect to its spatial distribution for various excitation conditions. The spectral characteristic of the light is compatible with an emission mechanism mediated by tipinduced plasmons that are excited by inelastic electron tunneling involving field emission resonances in the tip-sam...
متن کاملHeating Effect of Polycrystalline SiGe/Si Thin Films on Phase Transition of GeSbTe Films
This work reports the detailed manufacturing process of polycrystalline SiGe/Si thin film layers and their heating effect on phase transition of GeSbTe chalcogenide films. The SiGe and Si films were grown successively by chemical vapor deposition, and different methods were applied to dope the SiGe films depending on their semiconducting nature because of phosphorus autodoping. Although the min...
متن کاملNanomechanical study of amorphous and polycrystalline ALD HfO2 thin films
Thin films of hafnium oxide (HfO2) were deposited by atomic layer deposition (ALD). The structural properties of the deposited films were characterised by transmission electron microscopy (TEM) and X-ray diffraction (XRD). We investigated the effect of phase transformations induced by thermal treatments on the mechanical properties of ALD HfO2 using nanoindentation. The elastic modulus of the a...
متن کاملPolycrystalline indium-doped ZnO thin films: preparation and characterization
Zinc oxide (ZnO) and indium-doped zinc oxide (IZO) thin films have been deposited onto glass substrates by the spray pyrolysis method. The variations of the structural, electrical and optical properties with the indium incorporation were investigated. The crystal structure and orientation of the ZnO and IZO thin films were investigated by XRD patterns. All the deposited films are polycrystallin...
