Opis:: The X-ray standing wave technique has demonstrated in these last years to be a powerful method in the study of interfaces. In this paper the fundamentals of the technique will be given, together with examples of applications in the field of metal-semiconductor, of buried semiconductor-semiconductor interfaces and in structural studies of Langmuir-Blodgett films.

Opis:: To completely characterise the noise behaviour of a two port device, four noise parameters F(min), R(n), G(opt) and B(opt) must be determined. This paper reports improvements in the uncertainty related to the above parameters, taking into account measurement errors due both to the limited instrument precision and connection repeatability. Results are reported for noise characterisation of 0.3 žm delta-doped HEMT devices by Alenia, demonstrating as the common hot-cold measurement procedure can result with an error confidence as low as 0.2% for all the noise parameters.

Opis:: The crystal structure of the $(Bi_{0.02}Sr_{0.39}Ca_{0.59})_{10}Cu_{17}O_{29}$ spin-ladder compound was determined from single-crystal X-ray diffraction data. The precursor powder was prepared from stoichiometric amounts of $SrCO_{3},$ $CaCO_{3},$ $CuO,$ and $Bi_{2}O_{3}$ by calcination at 820°C for 20 h and pressed to form a rod used for the crystal growth. The travelling-solvent-floating-zone method was applied in an image furnace to grow large single crystals. The composite commensurate structure was solved and refined in space group F222, Pearson symbol oF224, a = 11.340(2), b = 12.829(2), c = 19.441(3) Å, Z = 4. The composite incommensurate structure of the $(Bi_{0.02}Sr_{0.39}Ca_{0.59})_{10}Cu_{17}O_{29}$ compound was solved and refined in the (3+1)-space group F222 (00γ), a = 11.340(2), b = 12.829(2), c_1 = 2.7773(4), c_2 = 3.8882(6) Å, q = 0.7143.
