From the optical emission, Ge-related oxygen deficiency centers (Ge-ODCs) are speculated to exist at a shallow depth. To clarify the creation depth of Ge-ODCs and roles of nanoparticles (NPs), Ge-oxidation states in the SiO2 layer and Ge NP were measured by two methods, i.e., X-ray photoelectron spectrometry (XPS) and 3-dimensional atom probe (3D-AP) after annealing: (1) in nitrogen gas flow at 700oC for 1h and (2) in air flow at 700oC for 1h. In XPS with Ar-etching, a significant increase of Ge-O bonds was shown at 15 30 nm in depth. Ge-Ge bonds decreased in the whole depth region. In 3D-AP, relatively large four Ge NPs were detected in the Ge-implanted SiO2 layer. The shallowest NP was spherical with at diameter of 5 nm and had a Ge-core at 2 nm in diameter and Ge-oxide shell of with 1 2 in thickness. So Ge-O bonds were surely created between core and shell. The role of Ge NP is to ensure forming G-ODCs in NP and interrupting progress of Ge oxidation to the deeper side.","PeriodicalId":23220,"journal":{"name":"Transactions-Materials Research Society of Japan","volume":"15 1","pages":"305-308"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85156794","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition, the impact of the cluster ions on a solid surface was investigated, and unique irradiation effects were found, such as the low-energy irradiation effect and the high-density irradiation effect. The kinetic energy of the cluster ion was converted to thermal energy, resulting in extremely high temperatures. Furthermore, the simultaneous use of chemical sputtering and thermal annealing processes was demonstrated with ethanol cluster ion beams. As a result, low irradiation damage and high-rate sputtering of Si surfaces was performed by the retardation potential method.","PeriodicalId":23220,"journal":{"name":"Transactions-Materials Research Society of Japan","volume":"274 1","pages":"217-224"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80008390","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Transparent electrodes such as indium tin oxide (ITO) are required, because light emission from the phosphor layer is necessary. To solve these issues, we developed a circular comb-type metal electrode with several narrow gaps on a glass substrate that produces a strong electric field, which is impossible to achieve with conventional structures. A comb-type metal (Au) electrode and a comb-type ITO electrode were used in the experiments. The luminance from the phosphor layer side at 30 V/μm was 26.9 cd/m for the Au electrode, which was twice that for the ITO electrode (19.9 cd/m). Thus, it is possible to fabricate a light-emitting device without transmissive electrodes by using a lustrous metallic material such as Au with a circular comb-type design.","PeriodicalId":23220,"journal":{"name":"Transactions-Materials Research Society of Japan","volume":"40 1","pages":"235-241"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74210698","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
