The aggregation of p-conjugated materials significantly impacts on the photophysics, and thus on the performance of optoelectronic devices. Nevertheless, we know comparatively little about the laws governing aggregate formation of p-conjugated materials from solution. In this talk, I shall compare, discuss and summarize how aggregates form for three different types of compounds, that is, homopolymers, donor-acceptor type polymers and low molecular weight compounds.

The Center for Nanoinetgration Duisburg-Essen (CENIDE) is a research center that focuses on nanoscience as the main research area of the University of Duisburg-Essen (UDE, Germany). Since 2005, CENIDE links the activities in natural science, engineering and medicine at the UDE that deal with the nano dimension.

Integrating high-performance III-V devices on the mature silicon platform has been a long pursuit over the past few decades. Direct epitaxial growth offers an alternative technology to bonding.  Using nano-patterned Si substrates, we created III-V on silicon templates with low defect density and smooth surface morphology for laser growth.  Such antiphase-domain (APD)-free III-V on silicon compliant templates with high crystalline quality (benchmarked by narrow XRD halfwidths) are grown without the need of special off-cut substrates and/or Ge buffer.

Mobile computing is experiencing a technological renaissance, and the Web is Florence. Throughout the past decade, the Web has redefined the way people retrieve information, communicate with one another, and extract insights. Although rife with opportunity, the energy-constrained nature of mobile devices is a major roadblock to the potential that next-generation Web technologies promise.

In this talk we'll present the latest results on the integration of silicon-photonic interconnects into a monolithic platform (45nm SOI logic process and bulk CMOS memory periphery process). These include world's first microprocessor communicating to the outside world with monolithically integrated Si-Photonic devices, as well as the first demonstration of photonics in a bulk CMOS process.

The production and use of engineered nanoparticles (ENP) inevitably leads to their release into aquatic environments. Concerns therefore arise over the possibility that ENPs might pose a threat to consumers and the environment. Investigations on the vulnerability of natural systems to ENPs are hampered by the absence of suitable analytical methods that are capable of detecting and quantifying ENPs in complex aqueous matrices. Analytical data concerning the presence of ENPs is therefore scarce.

I will discuss two main themes of research in my group addressing nano-photonics on silicon.  I will discuss recent advances on nanopillar devices based on III-V compound directly grown on silicon.

The UCSB Office of Technology & Industry Alliances is pleased to present a panel discussion of how to prepare for a successful and smooth launch of a new startup company - from assuring legal issues are in order to attracting and maintaining early investment.

Join the UCSB Photonics Society for their 2017 Light Science Workshop for a day of talks and presentations about the cutting edge in photonics research and career opportunities in this blossoming industry. The event will feature a keynote speaker, technical and non-technical presentations, Q&A panels, a job fair and a poster session!

The use of petroleum in transportation causes air pollution, water pollution, climate change, instability in energy markets, and other problems. In this talk, I draw on a wide range of energy, economic, environmental, and socio-demographic analyses to show that the best way to address these problems is to electrify transportation as part of an energy system based (almost) entirely on wind, water, and solar power.
