Cross-section view shows molecular density of the supersonic gas jet as it expands in vacuum and impinges onto a substrate, leading to accelerated material deposition from an energized adsorbed precursor. (Credit: Matthew R. Henry)

Colorized scanning electron microscope image shows the position of a resistive thermal device RTD (nanoscale thermometer) as the deposition substrate moves relative to the micro-size nozzle capillary for gas jet injection for mapping local temperature. The RTD thermal response was used for validation of the model prediction of the adatom non-equilibrium thermal state. (Credit: Matthew R. Henry)
