Clay works in the group of Prof. Lynn Loo on "Structure Development in Organometal Halide Perovskites for Thin-Film Photovoltaics."
Mapping the Crystalline Phase Space of a Molecular Semiconductor to Understand Effects on Charge Transport
Small molecules – be they pharmaceuticals, explosives, dyes, flavors for food, or, as the Loo Group studies, molecular semiconductors – can adopt a variety of crystal structures, a phenomenon known as polymorphism.
Grain boundaries act as bottlenecks to charge transport in organic field effect transistors comprising polycrystalline active areas. In the Loo Lab, we have found that the impact of these boundaries depends on the structure of the organic semiconductor (molecular or polymeric) and the method of thin-film formation (solution-processing or thermal evaporation).
Yueh-Lin (Lynn) Loo, Professor of Chemical and Biological Engineering and Deputy Director of the Andlinger Center for Energy and the Environment, will deliver an on-campus lecture on February 19 entitled “Ubiquitous Electronics through Conducting Plastics” as part of the President’s Lecture Series. Established by President Shirley Tilghman in 2001, the three President’s Lectures each year give Princeton’s faculty an opportunity to learn about the work of their
Yueh-Lin (Lynn) Loo, Professor of Chemical and Biological Engineering and Deputy Director of the Andlinger Center for Energy and the Environment, was recently named a Fellow of the American Physical Society (APS). Each year, newly-elected APS Fellows number no more than ½% of APS membership. Loo, who was recommended for Fellowship by the APS Division of Polymer Physics (DPOLY), was recognized “for elucidating the relationships between structure and function in conducting
In organic photovoltaic devices, the active layer—which absorbs sunlight to generate the electrons and holes which become the output current—has a delicate balancing act. It must simultaneously be thin enough that the electrons and holes can easily be collected, yet thick enough to absorb much of the solar radiation landing upon it. In an article entitled, “Wrinkles and Deep Folds as Photonic Structures in Photovoltaics”, published recently in Nature Photonics
In single crystals of organic semiconductors, charge carrier mobility can depend strongly on the crystal orientation, since mobility is typically much higher along the pi-stacking direction. But usually, the active layer in organic transistors consists not of a single crystal, but of a polycrystalline aggregate. CBE graduate student Stephanie Lee, working with Professor Yueh-Lin Loo and collaborators from the University of Kentucky, has studied large two-dimensional spherulites&mdash
Yueh-Lin (Lynn) Loo, Professor of Chemical and Biological Engineering and Deputy Director of the Andlinger Center for Energy and the Environment, has been chosen to receive the 2012 Owens Corning Early Career Award from the Materials Engineering and Sciences Division (MESD) of the American Institute of Chemical Engineers (AIChE). The award “recognizes outstanding independent contributions to the scientific, technological, educational or service areas of materials science and engineer
A multi-institutional international research team led by Yueh-Lin (Lynn) Loo, Professor of Chemical and Biological Engineering, and Takao Someya of the University of Tokyo (also in part-time residence at Princeton since 2009 as a Princeton Global Scholar) has created an organic transistor whose electronic characteristics are unchanged even after 20 sec of heating at 150°C, a temperature typically used to sterilize medical devices. These transistors, fabricated on a thin plastic film, a
The World Economic Forum has announced its Young Global Leaders (YGLs) for 2012, including Yueh-Lin (Lynn) Loo, Professor of Chemical and Biological Engineering and Deputy Director of the Andlinger Center for Energy and the Environment. This honor, bestowed each year by the Forum, recognizes up to 200 outstanding young leaders from around the world for their professional accomplishments, commitment to society, and potential to contribute to shaping the future of the world.
