Dr. Turak

Brief Biography

Dr. Turak is a member of the NSERC CREATE Program in Photovoltaics. Her research focusses on growth of organic and hybrid organic-inorganic (perovskite) thin films and nanoparticles for optoelectronics. In 2016, she was awarded an Early Researcher Award (ERA) for her work using nanoparticles to improve organic photovoltaics. Prior to her appointment at McMaster, she was a Marie Curie Fellow at the Max-Planck-Institute for Metals Research (2008-2010), then a visiting professor at Sabanci University in Istanbul, Turkey (2011), with a European Reintegration Grant for interfacial engineering of organic solar cells. She received her doctorate from the Department of Materials Science and Engineering at the University of Toronto in 2006, where she was a Canada Graduate Scholar working on organic light emitting diodes (OLEDs). She has received a Leadership in Teaching and Learning Fellowship (2017-2019) and the Petro-Canada Young Innovators award (2016). She is currently the co-chair for the Canadian chapter for the Society for Information Display, and on the Editorial Board for the Journal of Materials Science: Materials in Electronics (Springer) and Scientific Reports (Springer-Nature). She is a member of the Canadian Printable Electronics Industry Association/intelliFLEX Innovation Alliance, and a member of EVATEG (Energy Efficient Electronic and Lighting Technologies Research Centre, Turkey).

Interests:
Research:
organic semiconductor chemistry and structure, primarily for optoelectronics (organic light emitting diodes (OLEDs) and organic solar cells (OPVs));
surface and interface physics;
structural effects on surface activity, contact enhancement, and device performance;
order/disorder transitions in organic thin films;
inorganic MBE nanocluster growth;
reverse micelle nanoparticle microreactors
role of geometric packing in organic morphology
                 
Teaching:

Surface/interface physics and chemistry, both practical and theoretical;
Materials physics and chemistry, especially regarding structure and characterization;

Consulting/Collaboration expertise:
Dr. Ayse Turak is an expert in surface science and interfacial engineering, especially of organic(plastic)-inorganic(non-plastic) interfaces. Her major strengths are in the chemical, structural, and electronic properties of surfaces and interfaces. With 13 years of experience with physical vapor/molecular beam deposition in Ultrahigh vacuum systems, she is an expert in the manufacturing of a variety of material systems. Her expertise in characterization ranges from photoelectron spectroscopy  for chemical fingerprinting  and electronic (valence) structure determination, to x-ray scattering (x-ray reflectivity, x-ray diffraction) for crystal structure analysis, to scanning probe microscopies (atomic force microscopy, Kelvin probe microscopy) for morphological categorization. As an expert in organic optoelectronic devices, with nearly 15 years experience in organic electronics, she also has expertise in semiconductor parametric characterization for both light emitting (luminance-voltage, CIE coordinate determination, external quantum efficiency) and light absorbing (photocurrent, open-voltage, power conversion efficiency). Most of her experience is with hard to measure, low signal generating materials, so she is proficient in signal amplification techniques. Dr. Turak is interested in collaborative projects where she can use her expertise in materials an interfacial characterization to help companies understand and solve challenging problems in their products and processes.
