Growth methods of<i>c</i>-axis oriented MgB<sub>2</sub>thin films by pulsed laser deposition
High quality MgB2 thin films have been obtained by pulsed laser deposition both on MgO and on Al2O3 substrates using different methods. In the standard two-step procedure, an amorphous precursor layer is deposited at room temperature starting both from stoichiometric target and from boron target: after this first step, it …
