光电子能谱和密度泛函理论的研究表明，水在SnO2（101）表面上的解离吸附的终止氧原子的存在下，如果这些表面氧原子被删除的分子。这两种SnO2本体终端的不同化学表面响应也改变了水诱导的能带弯曲，从而改变了气敏材料的电导率。(c)2005 Elsevier B.V.保留所有权利。
Photoemission and density functional theory studies show that water adsorbs dissociatively on the SnO2(101) surface in the presence of terminating oxygen atoms and molecularly if these surface oxygen atoms are removed. The different chemical surface responses of these two bulk terminations of SnO2 also change the water induced band bending and consequently the conductivity of the gas sensing material.
