Abstract The strain dependence of the apparent activation energy of desorption of H 2 O on epitaxial, TiO 2 -terminated, out-of-plane polarized, BaTiO 3 (100) thin films has been investigated using X-ray diffraction, X-ray photoelectron spectroscopy and temperature-programmed desorption. The apparent activation energy of desorption increases significantly with the in-plane strain, suggesting that the strain-induced ferroelectric distortion determines the strength of the chemical bond between the dissociatively adsorbed water and the surface.

H2O 在外延应变、面外极化、BaTiO3(001) 薄膜上的解离吸附的应变依赖性

摘要 H 2 O 解吸的表观活化能对外延、TiO 2 封端、面外极化、BaTiO 3 (100) 薄膜的应变依赖性已使用 X 射线衍射、X 射线光电子光谱和程序升温解吸。解吸的表观活化能随着面内应变的增加而显着增加，这表明应变引起的铁电畸变决定了解吸水与表面之间化学键的强度。
