WebIn this system, more than 20 instruments such as photoemission electron microscopy (PEEM)/low-energy electron microscopy (LEEM), scanning tunneling microscopy (STM), X- ray photoelectron spectroscopy (XPS) and time-of-flight secondary ion mass spectrometry (TOF-SIMS), are interconnected by ultrahigh vacuum (UHV) tubes where samples can be … Photoemission electron microscopy (PEEM, also called photoelectron microscopy, PEM) is a type of electron microscopy that utilizes local variations in electron emission to generate image contrast. The excitation is usually produced by ultraviolet light, synchrotron radiation or X-ray sources. PEEM measures the coefficient indirectly by collecting the emitted secondary electrons generated in the electron cascade that follows the creation of the primary core hole in the absorption process. PE…
