Development of innovative organic semiconductors driven by state-of-art analytical instruments

Toshihiro Okamoto

Organic electronics based on organic semiconductors as an active layer have been extensively researched as next-generation electronic devices. To develop the market for organic electronic devices such as integration circuits and sensors, the carrier mobility (hereinafter referred to as the mobility) is an important parameter for device performance and needs to be improved significantly. Additionally, considering applicable organic electronics...

Various pole figure measurement techniques with SmartLab, assisting thin film characterization

Katsuhiko Inaba and Shintaro Kobayashi

A pole figure (PF) measurement is an X-ray diffraction (XRD) technique employed for the observation of textures in polycrystalline materials in the form of bulk ceramics, metal complex, thin films, etc, or the analysis of the orientation or domain configuration of epitaxial thin films. A comprehensive explanation of pole figures can be found in the technical...

Real-time analysis and display function using SmartLab Studio II

Takahiro Kuzumaki and Aya Ogi

X-ray diffractometry is widely used in R&D and quality control to investigate the crystal structure of materials. It has a diverse range of application, and is used not only for qualitative and quantitative analysis of powder samples, but also to evaluate the aggregate structure of metal materials, analyze the crystal orientation of thin-film samples, and so forth...

Introduction to single crystal X-ray analysis XIV. Model construction and refinement, and evaluation of results

Takashi Matsumoto

Single crystal X-ray structural analysis of proteins includes these steps: expression, crystallization of protein, data collection, phase determination, model building, model fitting, and refinement of the molecular model. When the difficult steps of crystallization and phase determination are overcome, the process of structural analysis can move on to model building and refinement. 

The initial electron density map...

X-ray fluorescence analysis of zinc and zinc-iron alloy coated steel sheet

Takao Moriyama and Kenji Kodama

Since it is possible to apply zinc to the surface of steel sheet in large quantities, hot-dipped zinc coated steel sheet is used for applications that require long period corrosion resistance, such as automotive bodies, prefab and metal buildings.

Zinc coated steel sheet can be roughly divided into zinc coated...

Automated multipurpose X-ray diffractometer SmartLab

SmartLab, which was announced as a thin film sample X-ray diffractometer in 2005, is a high-precision goniometer with a high-intensity X-ray source based on an innovative ergonomic design, and is widely used by many users. SmartLab has been updated several times in the 13 years since its launch. This year, an even more sophisticated model of SmartLab was introduced.

Multi-channel X-ray fluorescence spectrometer Simultix 15

X-ray Fluorescence Analysis (XRF) has been used in a wide range of fields as an instrumental analysis method that enables quick and easy elemental analysis. Compared with other methods, sample preparation is simpler and analysis accuracy is higher, and therefore it is not only used for quality control but also for research and development. 

Simultix is...

X-ray fluorescence spectrometer ZSX Primus400

X-ray fluorescence analysis is well-known as a non-destructive elemental analysis method. Sample preparation for the XRF technique can be performed quickly and easily, especially for solid samples. A wavelength dispersive type X-ray fluorescence spectrometer (WDXRF) has highly precise performance, so WDXRF is used for sample analysis in process and production control in many manufacturing industries. A sequential type...

Specialized, versatile, compact WDXRF spectrometer Supermini200 (RX9)

The benchtop wavelength dispersive X-ray fluorescent spectrometer Supermini200 and its predecessors have been on the market since 2000 and are being used on every continent in the world for research and industrial applications. Since its inception, demands for controlling lower levels of phosphorous (P), sulfur (S) and chlorine (Cl) have been on the rise. To meet these...
