摘要:

When analyzing an insulating organic ponder the application of an external potential difference to the sample holder results in shifts of different Magnitudes for the XPS lines of the sample and that of the sample holder. The same effect is observed when the bias voltage is applied to a metallic substrate covered with a very thin polymer layer. This technique permits the separation of the sample signals from that of the sample holder or the substrate.
