We investigated the interdiffusion of InGaAs/InP quantum wells (QWs) due to rapid thermal annealing (RTA) by photoluminescence (PL) spectroscopy and wedge transmission electron microscopy (WTEM). After RTA at temperatures between 650 and 900 degrees C (ann ...
Modern transmission electron microscopes offer imaging capabilities down to the atomic lattice resolution, as well as crystallographic and chemical microanalysis with 2-nanometer diameter probes in thin foils. These analytical microscopes are powerful tool ...
With the idea of operating the factors affecting the mobility or the pinning of ferroelectric domain walls in AB03 perovskites, high resolution electron microscopy has been performed to provide a better knowledge of the walls themselves in PbTiO/sub 3/. Th ...
The structures of the cubic, the tetragonal and the orthorhombic phases of single crystals of the ferroelectric aluminate sodalite Sr/sub 8/(Al/sub 12/O/sub 24/)(CrO/sub 4/)/sub 2/ were investigated by selected area and convergent beam electron diffraction ...
High-Resolution Electron Microscopy observations of gold particles are compared with images calculated using the multislice method for both regular f.c.c.-cuboctahedron- and Multiply-Twinned Particles -icosahedron, decahedron-. Although simulated for idea ...
