SEE coefficients of those aluminas with annealing process became lower after mechanical grinding operations even though its average roughness was almost same as those of as-sintered ones. SEE coefficients of mirror-finished samples were the smallest among the samples. Changes of SEE coefficient with incident angle of primary electrons for smooth and rough surfaces are also discussed, 2008年9月ルーマニア・ブカレスト開催 第23回ISDEIV『最優秀論文賞』受賞論文 Japan Prize-Best Paper Award, text, application/pdf}, pages = {97--100}, title = {Influence of Mechanical Finishing on Secondary Electron Emission of Alumina Ceramics}, year = {2006}, yomi = {スハルヤント and ヤマノウ, ヤスシ and コバヤシ, シンイチ} }
