Custom Calibration And Correction Of Photoemission Electron Microscope Images Using Graphene, Henry Bell
Macalester Journal of Physics and Astronomy
The Photoemission Electron Microscope (PEEM) is a full-field electron microscope that utilizes the photoelectric effect to image a surface. Due to a spatial resolution on the order of 10 nanometers and its ability to image both the morphology of a surface and its band structure, it is a useful tool for understanding the properties of materials for use in electronic devices. To correct for random sample misalignment and the experimental frame of reference in the spectroscopy mode of the PEEM, the 3D dataset must be rotated in both the momentum and energy coordinates which requires pixel calibration and energy alignment. …

Gas phase diatomic gold sulfide, AuS, was analyzed using optical spectroscopy. High-resolution spectra were collected and characterized and a global fit of the A2∑+-X2∏3/2 (0,0), B2∑–-X2∏3/2 (0,0), and C2Δ3/2-X2∏1/2 (0,0) transitions at 15570 cm-1, 16290 cm-1, and 17670 cm-1 was compiled and resulted in rotational constant determinations for the A2∑+((2σ)1(4π)4), B2∑–((2σ)2(4π)2(2σ*)1), and C2Δ3/2 …
