We present a detailed study of the interaction of chlorine with the Si(1 1 3) surface by means of scanning tunneling microscopy. Upon chlorine adsorption at a substrate temperature of 600 °C, the most prominent feature is the presence of (2 x n) rec

A Michelson interferometer for X-rays of wavelength ∼1 Å has been proposed to test the temporal coherence of FEL radiation. Such a device has been made at HASYLAB from a silicon single crystal. It is based on the BBB interferometer of Bonse and Ha

A theory of atom resolving X-ray fluorescence holography is presented. It uses the single-scattering approach to derive from Maxwell's equations a solution for imaging electron charge density distribution from the observed X-ray holography data. Expe

A silicon drift detector (SDD) was used for ex situ and time-resolved in situ fluorescence X-ray absorption fine structure (XAFS) on low-concentrated catalyst samples. For a single-element and a seven-element SDD the energy resolution and the peak-to

In this paper we investigate minority adsorption sites on Cl/Si(1 1 1)-(1 � 1) with the X-ray standing wave technique. By a combination with X-ray photon stimulated desorption,we show that the coordinates of the desorption-active chlorine minority

We have used Bi as a surfactant in Ge growth on Si(111) and present a detailed analysis of the adsorption site geometry of Bi on bare Si(111) as well as on ultrathin Ge films (1–2 monolayers, ML) grown on Bi-terminated Si(111). X-ray standing waves
