Dear Group,
We need to set up 3 personal meetings and find 1 more person for lunch.
Available times: 10:00–10:30am, 10:30–11:00am, 11:00–11:30am.
Best,
Dmitry

Dear Colleagues,
Dr. Brett Savoie (Northwestern U, Ratner Group) will be visiting our group
on November 5, 2013. His research interests include organic photovoltaics,
amorphous materials, and charge/energy transport in molecular networks.
There are five time-slots for personal meetings with Brett in the morning:
9:30 - 10:00am, 10:00 - 10:30am, 10:30-11:00am, 11:00 - 11:30am, and 11:30
- 12:00pm. Please make sure to pick one of these times, let me know, and
have your name in the schedule. We also need two (2) volunteers to join our
guest for lunch from 12:00pm till 1:30pm.
Everyone is strongly encouraged to attend Brett's talk at 2:00pm in the
Division Room. The title and abstract follow.
*Title:* "Electrons Climbing Trees: The Molecular Networks Responsible
for Charge Transport and Generation in Amorphous Organic Materials"
*Abstract:* In this talk, I'll walk through the principle challenges to
predictively designing amorphous organic materials, using organic
photovoltaic materials as an example. A springboard for this discussion is
the empirical observation that some structurally disordered organic films
manage to macroscopically transport energy and charge, even in the absence
of periodic order. I'll show how network theory is the natural language for
describing the inherent complexity and richness of these systems, and
discuss some recent results. Namely, a new methodology is developed that
utilizes network analysis to identify the hierarchical importance of the
many possible intermolecular interactions in the amorphous phase. On the
basis of results obtained from this methodology, it will be argued that the
functional robustness of certain families of organic materials to
structural disorder arises from their ability to create spatially extended
electrical networks.
Best,
Dmitry
