Electron Microscopy Laboratory dr hab. Franciszek Krok, prof. UJ Gronostajowa 3, room 022/028 Topics: - Interactions of electrons with matter - Principles of operation of scaning electron microscopy and transmission electron microscopy; - Structural and chemical examination of samples with SEM and TEM Examples: surface physics – metal deposition and self-assembling on semiconductor surfaces TEM microscope SEM/FIB microscope

Research topics: - Processes of self-organisation of metallic nanostructures on semiconductor substrate surfaces SEM image of Ag nanoisland grown on Ge(001) substrate surface SEM image (above) and STM image (below) of trianglar epitaxial Au islands grown on MoS 2 SEM image of nanoscale Au wires grown on InSb(001)

SEM image of pillars developed on InSb(001) surface under Ga + 30 keV ion beam irradiation (below the EDX spectra providing the chemical composition of the nanostructures) - Processes of ion-beam induced nanostructuring of semiductoctor crystal surfaces SEM image of nanodots array developed on InP(001) surface under irradiation with focus Ga + 30 keV ion beam

- SEM imaging of biological spesiments in the so called Environmental Scanning Electron Microscopy SEM image of leaf SEM image of lliposome SEM image of synamptosome
