The standard technique to deposition molecules in ultra-high vacuum (UHV) is evaporation/sublimation. However, evaporation is limited to volatile molecules, e.g. molecules that can be brought in the gas phase without decomposition by heating. Electrospray Ion-Beam deposition gives access to non-volatile molecules of different classes, such as biomolecules, dyes and other complex molecules and therefore expands the range of samples in UHV. Employing the possibility of mass spectrometry and subsequent mass filtering, highly pure samples can be fabricated.
In this poster, we will show an overview of the recent work performed with our home-built electrospray ion-beam deposition instrument in conjuction with STM.
