A gradient Si-rich oxide multilayer (GSRO-ML) deposition structure is proposed to achieve super-high density Si quantum dot (QD) thin film formation while preserving QD size controllability for better photovoltaic properties. Our results indicate that the Si QD thin film using a GSRO-ML structure can efficiently increase the QD density and control the QD size. Its optical properties clearly pro...

All plastics can be divided into two groups called thermoplastics and thermosets, and each group exhibits very different behaviors. Unlike thermosets, thermoplastics are empirically known by the viscoelastic behavior of the thermoplastic layers; the stress generated by building subsequent layers can be significantly relieved in a multilayer structure. In this study, we quantitatively investigat...

To bridge the gap between traditional multilayer and crystal optics a high-resolution multilayer monochromator with a bandwidth of 0.22% has been designed and installed on a bending-magnet beamline (F3) at the Cornell High Energy Synchrotron Source (CHESS) to provide an unfocused monochromatic X-ray beam for protein crystallography experiments. Crystallographic data of excellent quality from a ...

Understanding the structure of solid supported lipid multilayers is crucial to their application as a platform for novel materials. Conventionally, they are prepared from drop casting or spin coating of lipids dissolved in organic solvents, and lipid multilayers prepared from aqueous media and their structural characterisation have not been reported previously, due to their extremely low lipid ...

We proposed a 3D assembly technique and a perfusion cultivation system. The technique uses water transfer printing to fabricate a multilayer structured tubular tissue. By the perfusion cultivation system, this study was aimed to determine whether the tissue-engineered structure maintains the normally mechanical property as the development and function. In this work, we demonstrated that fabrica...

Photonics is a branch of science that studies how the light propagatesthrough the material and how to modify its propagation, such as how to prevent thepropagation or to localize the light, which can be useful to amplify the electric field. Toachieve this, one can use a system containing N layers of varying dielectric media inone dimension, which is called multilayer dielectric ...

[Fe (tFe) nm/Cu (tCu) nm]N multilayer films were prepared using pulsed-current electrodeposition method. The role of the pulsed-current deposition and Fe and Cu layer thicknesses on the magnetic properties was investigated. The microstructure of the multilayer films is dependent on the thicknesses of both the Fe and Cu layers. The saturation magnetization of the multilayers strongly correlated ...

Until recently, most microwave capacitors were based on fired multilayer ceramic technology. In this process, layers of highly conductive electrode metal alloys are interleaved with low-loss ceramic dielectrics in a multilayer fashion until the target capacitance is obtained. The resulting stack is then sintered into a monolithic structure in a high-temperature firing process. This process cont...

This paper aims to discuss the filter structures which constitutes a planar inductor, capacitors using microstrip lines and make it tunable taking the advantage of LTCC multilayer design. Investigations of passive multilayer filter structure using low-temperature co-fired ceramic (LTCC) for microwave and radio frequency application is studied. A roadmap for performance and process parameters to...

Influence of material anisotropy and gyrotropy on optical properties of fractal multilayer nanostructures is theoretically investigated. Gyrotropy is found to uniformly rotate the output polarization for bi-isotropic multilayers of arbitrary geometrical structure without any changes in transmission spectra. When introduced in a polarization splitter based on a birefringent fractal multilayer, i...
