Materials and Techniques in Astronomy and Particle Physics (abstract) J. Kennedy" and A. Woodcraft"'' "Scottish Universities Physics Alliance, Institute for Astronomy, University of Edinburgh, The Royal Observatory, Edinburgh, UK; UK Astronomy Technology Centre, The Royal Observatory, Edinburgh, UK Progress in fields such as astronomy and fundamental physics requires increasingly complex instrumentation operating at milhkelvin temperatures. Such instruments often place demands on materials and components not seen previously, particularly for space-based apphcations. The large scale of these projects and tight timescales necessitate the most conservative design possible. However, building these instruments with conventional techniques and materials is often impractical and sometimes impossible. It is therefore common for the design stage of such instruments to include test and measurement programs. These programs add risk to the development schedule, and suffer from the problem of tight focus on the exact needs of one particular instrument. We are setting up a laboratory to measure material properties and develop cryogenic components for general use in future large miUikelvin instruments. By decouphng these measurements from a particular instrument program, we have the freedom to make more speculative measurements, such as measuring new polymers whose cryogenic properties are completely unknown. We describe our set-up, plans for the future, and results of initial measurements.

Noncontact Conductivity M e a s u r e m e n t of Nanostructured Semiconductors Using T H z - T D S (abstract) Hyeongmun Kim", Inhee Maeng", Nam Ki Cho'', Jin Dong Song'', Won Jun Choi'', and Joo-hiuk Son" "Department of Physics, University of Seoul, Seoul, Korea; Nano Device Research Center, Korea Institute of Science and Technology, Seoul, Korea Four-point probe measurement has been commonly used to measure the electrical properties of nanostructured semiconductors. With this method, however, mechanical contacts are required and in some semiconductors, such as GaAs, it is difficult to characterize their electrical properties due to the Schottky barrier at the interface between metal and semiconductor.

Optical Properties of Nonlinear W a v e s Produced U n d e r Nonlinear W a v e Mixing (abstract) Hyun-Yong Kim, GeonJoon Lee, and InKyu Park Department of Physics, University of Seoul, Seoul, Korea Introducing two plain electromagnetic waves into nonlinear material, we can get another electromagnetic wave with frequency different from the two incident waves. We know the norms of same direction incidence case. ParaUel incident waves can be calculated simply with one-dimensional calculation. In this research, we examine arbitrary angle incidence cases by using the computational method. We arrived at two-dimensional findings and compared them with parallel incident case.
