<div>Hi all,</div>
<div>We have a user request for deposition of Barium from BaO powder using evaporation. The user is not too particular about the stoichiometry of the deposited film – both Ba or BaO or a mixture thereof are acceptable at this stage. I will try to make pellets
out of the powder before we evaporate. </div>
<div>I wanted to run it by the labnetwork community to see if there’re particular things to be careful about e.g.</div>
<ol style="margin:0;padding-left:36pt;">
<li>Should we use e-beam or thermal evaporation technique?</li><li>What kind of boat/crucible material should be used? </li><li>Any other important observations.</li></ol>
<div> </div>
<div>Finally, we also need to evaporate Cesium from a compound like CsF or CsNO3. Any input on evaporating Cesium from these or any other preferred compounds would be very useful.</div>
<div>Thanks.</div>
