We have developed a unique ultra-high vacuum instrument capable of analyzing samples via transmitted electrons in two complementary modes. These two modes are a standard microscopic regime in the range of energies from 5 keV down to few eV and a time-of-flight (ToF) method. Standard ToF spectrometers operate in energy range above 500 eV and detect reflected electrons. Our new ToF spectrometer is able to operate with energies of incident electrons below 300 eV. It detects transmitted electrons since the drift tube and detector are conveniently located below the analyzed sample. In order to apply these methods and interpret corresponding results correctly, deep understanding of electron transport phenomena in solids is required.
