Department / Organization: Chemical Engineering
Spectro-Nanoscopy of Ultrathin Films via Infrared Photo-induced Force Microscopy
Abstract: Ultrathin films of organic, inorganic, and biological molecules are utilized in many processes involved in production of nano-medicine, biosensors, and semiconductor devices. A non-invasive analytical technique that can verify the chemical and structural integrity of such thin films is presented in this talk. Infrared photo-induced force microscopy (IR PiFM) combines the two well-known techniques – atomic force microscopy (AFM for microscopy) and infrared absorption spectroscopy (IR for spectroscopy) – into one instrument to provide both structural imaging and IR spectro-nanoscopy with ~ 5 nm spatial resolution. A brief introduction to the technique along will various applications will be presented.
Dr. Park is the CEO of Molecular Vista, which he co-founded with Prof. Kumar Wickramasinghe (UC Irvine, formerly of IBM) in 2011 to provide research and industrial tools for rapid and nanoscale imaging with chemical identification. Sung has over 25 years of experience of industrial R&D, engineering, marketing and sales, and operations. He co-founded Park Scientific Instruments (PSI), which was one of the first commercial companies to develop and sell scanning tunneling microscopes (STM) and atomic force microscopes (AFM). Prior to founding Park Scientific Instruments, he worked as a post-doc at IBM Watson Research Center. Sung earned his Ph.D. in Applied Physics from Stanford University and BA in Physics from Pomona College.
