The amount of oxygen incorporated into MgB2 thin films upon exposure to atmospheric gasses is found to depend strongly on the material's stoichiometry. Rutherford backscattering spectroscopy was used to monitor changes in oxygen incorporation resulting from exposure to: (a) ambient atmosphere, (b) humid atmospheres, (c) anneals in air and (d) anneals in oxygen. The study investigated thin-film samples with compositions that were systematically varied from Mg0.9B2 to Mg1.1B2. A significant surface oxygen contamination was observed in all of these films. The oxygen content in the bulk of the film, on the other hand, increased significantly only in Mg rich films and in films exposed to humid atmospheres.

Superconductivity Induced in Iron Telluride Films by Low Temperature Oxygen Incorporation
我们报告的超导诱导膜的非超导，反铁磁母体材料FeTe的低温氧掺入在可逆的方式。X射线吸收表明，氧掺杂改变了名义Fe价态从2+在非超导状态，主要是3+在超导状态。因此，氧掺杂的FeTe中的超导性发生在与更常见的FeTe $_{1-x}$ Se $_x$完全不同的电荷和应变状态下。这项工作也提出了一个方便的路径进行掺杂实验原位与许多测量技术。

Stoichiometry control of magnetron sputtered Bi$_2$Sr$_2$Ca$_{1-x}$Y$_x$Cu$_2$O$_y$ (0$\le$x$\le$0.5) thin film, composition spread libraries: Substrate bias and gas density factors
采用磁控溅射方法制备了Bi_2Sr_2Ca_（1-x）Y_xCu_2 O_y（0 ≤ x ≤ 0.5）中组分随空间变化的薄膜库。用合适的掩模共溅射了Bi_2Sr_2YCu_2 O_{8.5 + δ}和Bi_2Sr_2CaCu_2 O_{8 + δ}两种成分的靶。靶掩模在相反但共线的径向方向上产生线性变化，并且衬底台的旋转速度足以使原子紧密混合。EDS/WDS组成的薄膜的研究表明，耗尽的Sr和Bi，这是由于氧阴离子再溅射。耗尽在膜的中心处（即与靶同轴）最明显，并且对称地下降到75 mm衬底的任一侧。在膜的任一边缘处，化学计量匹配所需的比率。使用比例为2：1的氩气和氧气的12毫托工艺气体，校正锶损耗。通过采用旋转碳刷装置向样品基底提供-20 V DC偏压来消除铋耗尽。负衬底偏压已成功地用于增加腔室压力，以消除整个膜的再溅射效应。结果是具有所需化学计量的薄膜组成散布库。
