摘要：

Influence of oxygen on electronic conduction in metal (In or Sb)-doped and undoped Csa films is investigated. The conductivity decreases by several orders of magnitude and the activation energy in semiconductor-like conduction highly increases due to oxygen absorption, and vice versa due to desorption. These variations are attributed to the oxygen-related electron trap states formed at about 0.7 eV below the conduction band.
