as well as excited type I and type II transitions, have revealed that a correct description of these heterostructures requires including the effect of the spin-orbit split-off states in the valence band physics as soon as the configuration of the electron-to-light-hole potential profiles switches...
Full size image The data in Fig. 4b is measured for the same gate values as in Fig. 4a, but at Φext = Φ0/2. In this configuration, the SQUID resembles an effective \(\sin (2\varphi )\) junction because the 2e supercurrent is suppressed. The energy relation for the appearance...
The measured full width at half maximum (FWHM) from the XRD rocking curves is obtained by rotating the sample through the Bragg angle after the angle (θ) and the detector position (2θ) are fixed at the Bragg angle of the corresponding reflection. The FWHM is used to determine ...

Schematic representation of the dislocation configuration in γ (disordered) and γ′ (ordered) Unalloyed single crystal Ni3Al is quite ductile, even at room temperature. In contrast, polycrystalline binary Ni3Al suffers from brittle grain boundaries....
The full-width at half-maximum (FWHM) value of X-ray rocking curve (XRC) of GaN layer grown on Al2O3 at 900 °C and 6% N2, was 27 and 338 arcsec for highly c-axis oriented columnar domains and disordered structure inside the GaN layer, respectively, for (0002) plane. The FWHM ...
Full size image Representative fine rosettes and cellular precipitates in coarse rosette region were characterized by scanning transmission electron microscopy (STEM) and energy dispersive x-ray spectroscopy (EDS) in Fig.2. The fine rosettes as shown in Fig.2a, c have Al3Ti cores surrounded by tw...
