Crystal Clear Imaging Infrared Brings to Light Nanoscale Molecular Arrangement


A team of researchers from Lawrence Berkeley National Laboratory (LBNL) and the University of Colorado–Boulder have developed a new way to reveal crystal features in functional materials for understanding not only their composition but also their molecular arrangement and microscopic imperfections. Using LBNL’s Advanced Light Source (ALS), they combined the power of infrared light from the ALS and infrared light from a laser with an atomic force microscope to reveal key nanoscale details about the nature of an organic semiconductor, revealing its crystal shapes, orientations, and defects that affect its performance.
