The materials data platform, DICE, plays a pivotal role in the imitative. As one of the DICE services, we offer the NIMS Materials Database (MatNavi) available via the internet to contribute to the development of new materials and material selection. The MatNavi is the world's largest and can be regarded as the one and only materials database. The Polymer DB, PoLyInfo, provides the information curated from academic papers such as the chemical structures of monomers and polymers, the physical properties, the polymerization conditions together with additional characterization data obtained by our own experiments. We offer two types of inorganic materials databases: AtomWork (free version) and AtomWork-Adv (paid version). The AtomWork-Adv have much more data than AtomWork as well as various viewing features and data download capabilities, which are not available in AtomWork. Both the Inorganic Material DBs includes crystal structures, phase diagrams, physical properties curated from academic papers. The Metallic Material DB, Kinzoku, provides the reliability information of commercially used metallic materials such as the creep and fatigue properties as well as the fundamental mechanical properties. These data are provided in the form of datasheet as the NIMS Structural Materials Data Sheets (4 types: creep, fatigue, corrosion, space use materials). Note that these data on metallic structural materials are obtained by our own experimental testing lasting over 40 years. In addition to the conventional use of searching and browsing material data and referring to the results, in recent years, data-driven research has attracted attention as a dataset for use in machine learning and other applications. To respond to these requests, we are considering and providing rules for the use of data as a single dataset.","" "Materials Data Repository metadata schema and cross-database federation","Materials Data Repository metadata schema and cross-database federation","松田 朝彦, 田邉 浩介, 石井 真史, 門平 卓也","松田 朝彦, 田邉 浩介, 石井 真史, 門平 卓也","17th European Congress and Exhibition on Advanced Materials and Processes (EUROMAT 2023)","17th European Congress and Exhibition on Advanced Materials and Processes (EUROMAT 2023)","2023-09-03","","eng","oral_presentation","","","","","","The Materials Data Repository (MDR) was released in 2020 as one of the services of the DICE materials data platform. Works deposited to MDR are assigned DataCite DOIs, allowing integration with external services such as Data Citation Index. Significant effort was devoted to implement a metadata schema with a focus on PIDs and support for specimen, methods, and instrument metadata. A YAML-based schema was adopted, developed alongside a new system to natively support the new schema. The new UI works in conjunction with NIMS's research registration system and makes use of CrossRef API, minimizing metadata input from researchers. Using works deposited to MDR as instances, we can define an ontology for data linking and federation. The work instance can be linked to triple graphs for both XAFS and HAXPES while retaining the schema.

However, there is an issue of interface states due to the formation of GeOx. GeOx is chemically unstable and a low dielectric material. To overcome this issue, we have proposed the direct growth of CeF3 on Ge (100). CeF3 is used as optical materials such as the reflection coating and scintillator. CeF3 also has wide bandgap (~4.3 eV) and high dielectric constant (> 30) properties, which should be suitable for the gate insulator, and is expected to eliminate the oxidization at the CeF3/Ge interface. In this work, we investigated the interface structure at the CeF3/Ge interface by hard x-ray photoelectron spectroscopy (HAXPES), and developed the Ge diffusion barrier layer by combinatorial method. HAXPES revealed that the band alignment between CeF3 and Ge was estimated as ΔEC = 0.9 eV.

Early failure simulations are performed using the recently developed “lucky defect” model. The model shows the bulk defects in the gate oxide as the culprit for early TDDB failures through an increase in tunneling current via trap-assisted-tunneling (TAT). We show that an exponential distribution of “lucky defects” in the oxide bulk affects the failure distribution in a similar fashion to what we observed experimentally. We also identify the implications of under-sampling the population in these extrinsically dominated failure distributions.

For example, Pt and Ni are typical metals used for Schottky contacts, while Ti is regularly used for Ohmic contacts on GaN. After deposition, the metal/GaN stack is usually annealed during a sintering process but resulting Ohmic contacts and Schottky barrier heights at the interface are found to be highly dependent on annealing temperature,[3] are not very stable upon extended heating,[4,5] and are not very reproducible.[6] As one of the most fundamental GaN contacts, this issue requires close inspection.To reve" "Epitaxial grwoth of GaN on Si with buffers for future devioces","Epitaxial grwoth of GaN on Si with buffers for future devioces","知京 豊裕, ギュエン ナム, 松田 朝彦, 屋山 巴, 長田 貴弘, ジョ ユージン, 関口 隆史, 上杉健二郎, 布上 真也, 福島 伸, 寺本 喬, Christian Dussarrat, 木村 貴子","知京 豊裕, ギュエン ナム, 松田 朝彦, 屋山 巴, 長田 貴弘, ジョ ユージン, 関口 隆史, 上杉健二郎, 布上 真也, 福島 伸, 寺本 喬, Christian Dussarrat, 木村 貴子","INC12","INC12","2016-05-09","","jpn","oral_presentation","","","","","","","Wide band gap III nitride semiconductor of GaN have attracted much attention because of their excellent optical and electrical properties for optical device.

Considering the ubiquity of this material system, this is a crucial issue that needs to be resolved. In order to address this, we utilized a variant of the charge pumping method. Applying the transition state theory to the capture reaction, we directly associated the energy change during the reaction with the extracted time constants. Discussing experimental results with this relationship reveals the source of the aforementioned confusion. This analysis shows that the understanding based on reaction kinetics and appropriate physics is crucial in understanding the physical nature of the traps in a meaningful manner."
