| Abstract: | A silver film is deposited onto polyethylene thin film by silver mirror reaction.Grazing incidence X-ray diffraction with different incident angles is used to characterize such thin film.By comparing the experimental results and theoretical calculations,it is confirmed that the equation derived from smooth interface can be used to calculate the X-ray penetration depth. |
| Keywords: | X-ray diffraction penetration depth grazing incidence polyethylene thin film |
