Marek Malac

Senior Research Officer, National Institute for Nanotechnology

Adjunct Professor, Department of Physics, University of Alberta

Dr. Malac’s electron microscopy research is focused on pushing the boundaries of understanding of physical principles underlying electron microscopy, developing instrumentation and methods for data interpretation. His work is motivated by the need to quantitatively analyze practical, radiation-sensitive, materials at and to visualize and quantify scientific problems at nanoscale. Dr. Malac’s work extends, often in collaboration with Hitachi High Technologies and JEOL USA, Ltd., many aspects such as instrument optimization and implementation of new data collection methods, development of phase shifting devices, various in-situexperiments, and custom sample holders. He led the effort to acquire and set up NINT’s state-of-the-art electron microscopes. He also leads several electron microscopy development projects of the Hitachi Electron Microscopy Development Centre (HEMIC) at NINT including phase plate development collaboration with JEOL USA and the scientific aspect of the development of new quiet laboratory at NINT.

His research interests are focused on improving phase-retrieval methods in a transmission electron microscope (TEM), developing experimental methods for measurement of optical and dispersion relations at nanoscale using electron energy loss spectroscopy (EELS) for quantitative measurements, and extending the practical interpretation of ELNES beyond fingerprinting to unscrambling information from ELNES. Core-loss EELS provides information about chemical composition and bonding at nearly atomic length scale, but interpretation of the spectral data is difficult.

Other research goals include maximizing the amount of interpretable information per unit irradiation damage of the sample by developing new methods and instrumentation, and reducing the effect of uncertainties of data acquisition steps and resolution limiting methods in electron tomography to retrieve the 3-D morphology at nanoscale by using new methods.

He is working to understanding the physical limits of Focused Ion Beam (FIB) fabrication and characterization to develop new and optimize existing methods for nanoscale prototyping and analysis, and develop instrumentation for enabling practical application of an improved understanding of limits of electron microscopy and FIB.
