Spectromicroscopy with Low-Energy Electrons: LEEM and XPEEM Studies at the Nanoscale

Low Energy Electron Microscopy (LEEM) Imaging of a Neuron Network

The feasibility of using the LEEM technique in neurobiology was tested with experiments on a rat cerebellar granule cell culture. A series of goodquality images, showing h e details such as axons and dendrites of the neuron network, demonstrate that the test was successful. A new series of microscopy techniques is being developed, with complementary techniques and considerable advantages in lif...

Collisions of low-energy electrons with isopropanol

We report measured and calculated cross sections for elastic scattering of low-energy electrons by isopropanol (propan-2-ol). The experimental data were obtained using the relative flow technique with helium as the standard gas and a thin aperture as the collimating target gas source, which permits use of this method without the restrictions imposed by the relative flow pressure conditions on h...

Holography with Low Energy Electrons: Principles and Applications

The concept of holography with low energy electrons is described in view of its applications in molecular biology. The challenges and difficulties associated with Gabor type holography are outlined and the differences between coherent electron beams of high and low kinetic energy are discussed. The properties of the coherent electron point source for low energy electrons are reviewed as well as...

LOW-ENERGY-ION ENHANCED DIFFUSION AT THE SURFACE OF METALS

Radiation enhanced diffusion at the surface of metals has been observed and studied for low-energy nitrogen ions at the surface of copper. The displacement of the target atoms during irradiation creates vacancies and other defects near the surface, thus enhancing the diffusion of implanted materials toward the surface and also into the solid. The mechanism has been studied here by a specia...
