The surface of La1/3Ca2/3MnO3 (LCMO) films with thickness, t, ranging from 4 to 150 nm has been studied. Highly ordered palpus-like crystals induced by strain are observed in the films grown on the substrate of SrTiO3 (with thickness t ranging from 20 to 50 nm) and on sapphire (with thickness t...

Effects of Si3N4 passivation layer on the lattice strain of Al0.22Ga0.78N layer with the thickness of 100 nm has been studied by in situ X-ray diffraction by the temperature range of 25°C–550°C. Results show that the temperature dependence of the strain relaxations can be separated into...
