Foreword

Abstract
The Workshop on Low Temperature Electronics (WOLTE) is intended to permit scientists and engineers working in the field of advanced materials, technologies, devices, circuits and systems for low temperature electronics to highlight and discuss the latest research and development results. This is the fifth Workshop of a series started in 1994 in Grenoble, France (WOLTE-1), followed by WOLTE-2 in 1996 in Leuven, Belgium, WOLTE-3 in 1998 in San Miniato, Italy, and WOLTE-4 in 2000 in Noordwijk, The Netherlands. The main themes of this meeting are ranging from physics and fundamental aspects, modeling and simulation, to device and circuit design. The topics include advanced process and characterization, novel devices and cryogenic instrumentation. The papers in this proceedings volume of WOLTE-5 are divided into 9 sections, reflecting the main research efforts in different areas: i) Silicon MOSFETs, ii) Alternative MOSFETs, iii) III-V devices, iv) Other Semiconductor Devices, v) Emerging Devices and Phenomena, vi) Superconducting Materials, vii) Superconducting Detectors, viii) Superconducting Devices and Circuits, ix) Low Temperature Electronics for Space Applications. The Workshop program features 6 invited papers presented by internationally recognized authors, and 39 contributed papers. The invited papers provide an excellent overview of today's status and progress, as well as tomorrow's challenges and trends in this important discipline for many applications.

WOLTE-5 is organized by IMEP (Institut de Microilectronique, Ilectromagnitisme et Photonique), a laboratory of the "Institut National Polytechnique de Grenoble" associated with the "Centre National de la Recherche Scientifique" and "Universiti Joseph Fourier". The Organizing and Programme Committees are composed of 17 International Scientists from 8 countries. They all share a worldwide recognition. The Organizer would like to thank them for their help and support in reviewing the abstracts and in proposing invited speakers, which both guarantee the scientific level of the meeting. We are also grateful to the session co-chairs, and to the authors for their effort in preparing and presenting the high quality papers that form the foundation of the WOLTE Workshop. We would also like to thank all the sponsors for their support to the organization of this fifth European Workshop on Low Temperature Electronics.

This year a Short Course preceding and complementing WOLTE-5 on "Ultimate Electronic Devices and Sensors" is organized in collaboration with "Centre International de Rencontres Pluridisciplinaires de Grenoble Pole Europien". D. Feinberg (UJF, Grenoble), B. Pannetier (CNRS, Grenoble), J.C. Villegier (CEA, Grenoble) and myself have actively participated in the organisation of this short course opened to all WOLTE-5 participants.

We also would like to thank Sylvie Mercier, from IMEP, for social and technical arrangements and for her help in organizing this book.

On behalf of the Organizing and Program Committees, it is our great pleasure to address a warm welcome to all authors and attendees of WOLTE-5.
