WebThe penetration depth is limited to few atomic layers and is almost constant when the incidence angle is lower than the critical angle (u0002c). In the case of gold at u0002 < 0.4u0001 , the pene- tration depth is about 15 A ˚ and drastically increases when u0002 > u0002c (for gold at 1u0001 of incidence it is about 400 A ˚ ). Webpenetration depth is limited to several nanometres depending on the incidence angle, the wavelength of the radiation and the electron density of the material (Vineyard, 1982). Therefore, in a GIXD experiment the evanescent wave is scattered only by the first few surface layers, resulting in an exceedingly increased surface sensi-tivity.
