Optimum HRTEM image contrast at 20 kV and 80 kV--exemplified by graphene.

The dependence of high-resolution transmission electron microscopy (HRTEM) image contrast of graphene on the adjustable parameters of an aberration-corrected microscope operated at 80 and 20 kV has been calculated and, for 80 kV, compared with measurements. We used density functional theory to determine the projected atom potential and obtained the image intensity by averaging over the energy d...

Semileptonic decays B\pln and D\pln from lattice QCD

We present a lattice QCD calculation of the form factors and differential decay rates for semileptonic decays of the heavy-light mesons B and D to the final state pln . The results are obtained with three methodological improvements over previous lattice calculations: a matching procedure that reduces heavy-quark lattice artifacts, the first study of lattice-spacing dependence, and the introduc...

Kritische Betrachtung des Löschverhaltens in kompensierten 20-kV-Netzen

Emanuel Fuchs 11 Furthermore a new method for the automated evaluation of earth faults is introduced. The new method determines the detuning and the damping, based on the decay process, in the frequency domain. For the automated evaluation of earth faults the accurate registration of the distinguishing moment of an earth fault is necessary. For the accurate registration a new method is introduc...

Transmission electron microscopy at 20 kV for imaging and spectroscopy.

The electron optical performance of a transmission electron microscope (TEM) is characterized for direct spatial imaging and spectroscopy using electrons with energies as low as 20 keV. The highly stable instrument is equipped with an electrostatic monochromator and a C(S)-corrector. At 20 kV it shows high image contrast even for single-layer graphene with a lattice transfer of 213 pm (tilted i...
