摘要：

A remarkable ambient effect on the resistance of CVD diamond during cooling after deposition has been observed. The diamond films that were cooled slowly down to room temperature (RT) in the 10(-3) Torr range after deposition showed relatively low resistances in the range of 10(6) is similar to 10(7) OMEGA. On the other hand, high resistances over 10(3) OMEGA were observed for diamond films that were cooled down to RT in an oxygen or an air ambient and at atmospheric pressure. Among these surfaces a substantial difference was observed in the electronic structure as studied by electron energy loss spectroscopy.
