自発分極は試料内部の静電ポテンシャルを傾斜させる。強誘電体の原子軌道エネルギーはこの傾斜に応じて系統的に変化すると考えられる。この現象はバンドベンディングと呼ばれ40年以上に渡り予想されてきた。今回，BaTiO_3_においてバンドベンディング現象を直接的に観測したので報告する。本研究において得られた実験結果は，エピタキシャル製膜された強誘電体薄膜試料と深さ分解光電子分光実験を組み合わせることで初めて達成できた。

Bi_2_SiO_5_は室温以上で強誘電性を示すシリケート化合物である。本研究ではBi_2_SiO_5_中のBiをLaで1%〜10%置換した試料を作製し、誘電率測定を行った。その結果、La置換による相転移のブロード化が観測され、置換率3％で相転移が消失した。相転移が消失した試料では100〜500 Kにわたって温度変化がほとんどない、高誘電率(ε' 〜 100)が得られた。講演では、誘電応答の起源を格子ダイナミクスの観点から議論する予定である。
