Note that the upper critical field in the limit of zero temperature of the 1/1AC_F (H_{\tt c2}(0) \cong 500 Oe) substantially exceeds that of metal Al (\sim 100 Oe), excluding the possibility that the superconductivity would arise from Al-derived impurity phase Full size image The ...
in high temperaturein situstraining experiments in a high voltage microscope[3]. Dislocations have never been observed in glasses because no diffraction contrast mechanism, needed for visibility, exists in a long-range disordered material. Fortunately, a large conceptual advance in the field has been...
To numerically solve these integral equations, an expansion method using orthogonal Chebyshev polynomials is employed. The results provide insights into the interfacial stresses, axial force, as well as axial and vertical deformations of the PQC film. Additionally, fracture criteria, including stress ...
In addition, we take into account surface elasticity theory in order to obtain the phase velocity equation based on the wavenumber expression. The model incorporates surface elasticity, piezoelectricity, and permittivity to account for nanoscale surface phenomena. Two configurations are examined: an ...
HAADF-STEM was performed on a CS-corrected FEI Titan Themis 200 microscope operated at 200 kV (Schottky XFEG cathode, 0.08 nm point resolution; image conditions: 17.6 mrad probe (half) convergence angle with 70 pA probe current, 69–200 mrad annular dark field detection angle)...
Structural Study of an Al 72Ni 20Co 8 Decagonal Quasicrystal Using the High-Angle Annular Dark-Field Method High-angle annular dark-field (HAADF) images of an Al72Ni20Co8 decagonal quasicrystal have been taken for the first time. It has been found that the transi......

The magnetization of the lattices was analyzed using LTEM with the sample sitting in a field-free region26. In order to reconstruct maps of the in-plane magnetic induction from the phase shift of the incident electrons, through-focus series consisting of at least nine BF TEM images were ...

Although the method itself does not using directly eigenstates of the Hamiltonian, it is equivalent to the standard Kubo formulation which calculates excitations between ...
