New Technique Development


Methods for Conducting Electron Backscattered Diff raction (EBSD) on Polycrystalline Organic Molecular T in Films by K Abbasi, D Wang, MA Fusella, PB Rand, and A Avishai, Microsc Microanal | doi:10.1017/S1431927618000442


Electron backscattered diffraction (EBSD) is a technique regularly used to obtain crystallographic information from inorganic samples. When EBSD is acquired simultaneously with EDS data, a sample can be thoroughly characterized both structurally and compositionally. For organic materials, coherent Kikuchi patterns do form when the electron beam interacts with crystalline material. However, such patterns tend to be weak because of the low average atomic number of organic materials. This is compounded by the fact that the patterns fade quickly and disappear completely once a critical electron dose is exceeded, inhibiting successful collection of EBSD maps from them. In this study, a new approach is presented that allows successful collection of EBSD maps from organic materials; here the extreme example of a hydrocarbon organic molecular thin film is presented, which opens new avenues of characterization for crystalline organic materials.


EBSD patterns can be achieved from polycrystalline organic molecular thin fi lms using the proposed approach. These patterns can be then used to produce crystallographic orientation maps. Each grain has a specifi c orientation. Two of the grains are shown with their respective EBSD patterns.
