酸塩基ヘテロ接触の電気抵抗に及ぼす水蒸気の効果

抄録

Surface electrical resistance along the interface of acid base hetero-contact using TiO₂ or NiO substrate was measured at 20°C under controlled humidity. Humidity-sensitivity of acid TiO₂ was suppressed by the contact with basic oxides and that of basic NiO was enhanced by the contact with an acid oxide. A model in which protons transfer from acid to basic surface by acid base interaction was proposed.
