High - J _c superconducting Bi₂Sr ₂CaCu ₂O _8+δ thin films:Analysis of elemental composition, phase and microstructure

Description

Bi₂ Sr ₂ CaCu₂ O _8+δ (Bi-2212) thin films with thickness less than 50 nm are grown
by pulsed-laser deposition (PLD) technique. The elemental composition, phase
purity, and microstructure of films are analyzed by electron spectroscopy (EDX,
AES, XPS), electron microscopy (SEM, TEM) and X-ray diffraction (XRD). The
superconducting properties are determined by measurements in magnetic fields
and fits of theoretical models to the measured data. Bi-2212 films grown on
LaAlO 3 substrates and annealed in-situ at temperature T > 700 °C partially
decompose into non-superconducting impurity phases (Fig. 1).
