The theory and practical limitations of micro area scanning transmission electron diffraction (MASTED) will be presented. It has been demonstrated that MASTED patterns of metallic thin films from areas as small as 30 Åin diameter may be obtained with the standard STEM unit available for the Philips 301 TEM. The key to the successful application of MASTED to very small area diffraction is the proper use of the electron optics of the STEM unit. First the objective lens current must be adjusted such that the image of the C2 aperture is quasi-stationary under the action of the rocking beam (obtained with 40-80-160 SEM settings of the P301). Second, the sample must be elevated to coincide with the C2 aperture image and its image also be quasi-stationary. This sample height adjustment must be entirely mechanical after the objective lens current has been fixed in the first step.

Silicon-on-insulator (SOI) structures have excellent potential for future use in radiation hardened and high speed integrated circuits. For device fabrication in SOI material a high quality superficial Si layer above a buried oxide layer is required. Recently, Celler et al. reported that post-implantation annealing of oxygen implanted SOI at very high temperatures would eliminate virtually all defects and precipiates in the superficial Si layer. In this work we are reporting on the effect of three different post implantation annealing cycles on the structure of oxygen implanted SOI samples which were implanted under the same conditions.

The Bronze Age

General archaeological accounts of Scotland tend to demonstrate broad ideas of the Neolithic transition to farming and the subsequent economic changes in the Bronze Age. Whilst they concentrate on important economic and cultural advancement they tend to lack discussions on cosmological change. This paper looks at one small area in Aberdeenshire to examine four different classes of monument that are found there: long mounds and long cairns; Recumbent Stone Circles; henges and Beaker burial sites. It argues that skyscape archaeology, through the use of archaeoastronomical techniques, can provide clues to cosmological change.
