Dr. Soci received his Laurea degree and his Ph.D. in Physics from the University of Pavia in 2000 and 2005, respectively. He was a postdoctoral researcher at the Center for Polymers and Organic Solids at the University of California - Santa Barbara in 2005-06 and at the Electrical and Computer Engineering Department at the University of California - San Diego in 2006-09. In August 2009 he joined the Nanyang Technological University as a Nanyang Assistant Professor at the Schools of Physical and Mathematical Sciences and Electrical and Electronic Engineering.
Research Interests
We are interested in the fundamental properties of materials related to small dimensionality and large interface area. Understanding these properties is essential to exploit them in emerging technologies, such as renewable energy sources. In particular we focus on two classes of nanostructured materials, namely organic and inorganic semiconductors, and on their interplay, from basic scientific issues all the way to the device level. Some topics of specific interest are:

1. Nanowire synthesis and devices: semiconductor nanowires are synthesized by different approaches, including top-down and bottom-up methods, and lithographic techniques are used to fabricate nanowire arrays and devices.

2. Organic semiconductors: we study the fundamental properties of organic semiconductors and their use in "plastic electronics." In particular we focus on the interplay between charge carrier photogeneration and exciton recombination, which is a determining factor of the performance of organic solar cells, light-emitting diodes and field-effect transistors.

3. Organic-inorganic hybrid systems: we investigate the optoelectronic properties of hybrid organic-inorganic heterostructures specifically targeted to light sensing and photovoltaic applications, combining microscopy, optical and photocurrent spectroscopy, and nanofabrication technologies.
