The conduction processes in ZnO varistors is clarified. By adjusting additive type and amounts in ZnO the electrical properties of ZnO varistors can be controlled. Based on this recipe, Y, Cr, Ni, B, Si oxides were added in this study. These oxides can be divided into two categories, the Y doping group and the Si doping group. eng doctoral thesis VoR https://doi.org/10.14988/00028853 https://doshisha.repo.nii.ac.jp/records/28861 10.14988/00028853 BD00905871 https://doors.doshisha.ac.jp/opac/opac_link/bibid/BB13204503/?lang=0 掲載刊行物所蔵情報へのリンク ／ Link to Contents 甲第1215号 博士(工学) Doctor of Philosophy in Engineering 2022-03-22 34310 同志社大学 Doshisha University https://doshisha.repo.nii.ac.jp/record/28861/files/k1215.pdf application/pdf 412.3 kB 2022-04-18 https://doshisha.repo.nii.ac.jp/record/28861/files/zk1215.pdf application/pdf 8.4 MB 2022-12-20
