The electron beam, which is depicted as a dotted line, hits the surface of the sample. The sample emits ejected sample electrons and transmitted beam electrons through the opposite side, both depicted by dotted lines slightly off angle to the path of the incoming electron beam. Emitted X-rays reflect off the surface of the sample, represented by a wavy line in order to indicate that this is a form of energy.<\/p>\n<p><strong><em>Captions included on the image:<\/em><\/strong><\/p>\n<ul>\n<li>Energy dispersive X-ray spectroscopy (EDS, also abbreviated EDX, XEDS, or EDXS) measures the energy of X-rays released from a sample\u2019s surface when it\u2019s irradiated by an electron beam.<\/li>\n<li>Electron energy-loss spectroscopy (EELS) measures the energy of electrons that pass through the specimen as they inelastically collide with the sample\u2019s electrons.<\/li>\n<\/ul>\n<p id=\"figure2\">\n<strong>Image 2 Title: What happens?<\/strong><br \/>\nThis figure is split into two halves, with EELS information on the left and EDS information on the right. An illustration depicting the interaction of a beam electron with a sample atom is shown in both columns, but with different elements emphasized, depending on what is relevant to the technique. The atom is represented by a stylized nucleus surrounded with two concentric rings of electrons. The inner ring has 2 electrons and the outer ring has 6 electrons.<\/p>\n<p>One of the inner ring electrons is struck by a source beam electron and knocked off of the atom, with an empty circle representing its absence. The source beam electron is deflected off of this empty circle and is now labeled as an EELS electron. An electron on the outer ring has an arrow pointing toward the empty circle, indicating that it will fill this vacant position. A wavy line, representing an emitted X-ray, is shown pointing away from the atom as a result of the outer ring electron moving to the inner ring.<\/p>\n<p><strong><em>Captions included on the image:<\/em><\/strong><\/p>\n<ul>\n<li>EELS: An electron beam inelastically impacts a sample atom and EELS subsequently detects this electron as it leaves with a reduced energy that depends on the electron shell it interacted with.<\/li>\n<li>EDS: An electron beam inelastically impacts a sample atom and a core shell electron is knocked off. A higher energy electron fills the hole left behind in order to stabilize the atom. The difference in energy of this electron\u2019s initial and final position is released as an X-ray. EDS detects this X-ray, which has a specific energy characteristic of that electron transition.<\/li>\n<\/ul>\n<p id=\"figure3\">\n<strong>Image 3 Title: What does this tell you?<\/strong><br \/>\nThis figure is split into two halves, with EELS information on the left and EDS information on the right.<\/p>\n<p>The left column shows an idealized EELS spectrum, with electron energy loss (in eV) on the x-axis and relative frequency on the y-axis. There is a tall zero loss peak on the far left, followed by a slightly shorter and broader plasmon resonance peak. An inset shows a close up of the right portion of the spectrum. The inset contains the relatively small atom core-loss peak, to its right are smaller peaks that correspond to fine structure information.<\/p>\n<p>The right column shows an EDS spectrum of a mineral sample, with energy (in keV) labeled on the x-axis and no y-axis label. Numerous peaks are individually labeled with the element they correspond to: the most prominent include a carbon peak on the far left followed by an oxygen peak that is approximately twice as tall. On the far right is a prominent iron peak that is slightly shorter than the oxygen peak.<\/p>\n<p>Both images are attributed to Wikimedia Commons user Hat\u2019nCoat under Creative Commons BY 3.0.<\/p>\n<p><strong><em>Captions included on the image:<\/em><\/strong><\/p>\n<ul>\n<li>EELS: The low-energy peak corresponds to interactions with weakly bound outer shell electrons. The high-energy peak corresponds to collisions with the core shell electrons. The fine details of these two peaks can provide information on the atom of origin and its bonds to its neighbors.<\/li>\n<li>EDS: The peaks of an EDS spectrum correspond to the unique electron transitions in the atom of origin. The ratios of the peaks give insight into the relative amount of each element in the sample.<\/li>\n<\/ul>\n<p id=\"figure4\">\n<strong>Image 4 Title: Comparison of EELS and EDS<\/strong><br \/>\nThis figure is split into two halves, with EELS information on the left and EDS information on the right.<\/p>\n<p>The left column shows a core-loss EELS atomic-resolution elemental map of a BaTiO\u2083\/SrTiO\u2083 interface.<\/p>\n<p>The right column shows an SEM image of electroplated bimetallic metal foams colorized with EDS data.
