We have investigated the thermodynamic and kinetic barriers involved in the synthesis of MgB2 films. This work refines our initial conjectures predicting optimal MgB2 thin film growth conditions as a consequence of the unusually large kinetic barrier to MgB2 decomposition. The small Mg sticking coefficient at temperatures greater than 300 °C prevents high temperature synthesis with traditional vacuum growth methods. However, as a result of the large kinetic barrier to MgB2 decomposition, in-situ thermal processing can be used to enhance the crystallinity and the superconductivity of MgB2 films. We used these methods to produce MgB2 thin films with relatively high transition temperatures (∼37 K) by pulsed laser deposition (PLD).
