The 2015 International Conference on Noise and Fluctuations (ICNF 2015),co-sponsored by the IEEE Electron Devices Society and Xidian University, will be held from 2 to 5 June2015, in the beautiful, historic city of Xi’an, CHINA. The aim of this biennial conference is to bring together specialists in fluctuation and noise phenomena from different fields in science, engineering and business, including material, electronic and optoelectronic devices, sensors, mesoscopic systems and nanostructures, analog and digital circuits and systems, complex systems, biological and biophysical systems, social and financial systems, reliability, to address both fundamental and applies issues. The International Conference on Noise and Fluctuations (ICNF) is a biennial event. The recent past 10 conferences in this series were organized in Palanga (1995), Leuven (1997), Hong Kong (1999), Gainesville (2001), Prague (2003), Salamanca (2005), Tokyo (2007), Pisa (2009), Toronto (2011) and Montpellier (2013).
