Define Surface Contaminations (Wisconsin-Madison)?
A surface scientist wishes to remain an exposed surface "clean" (≤ 0.05 adsorbed monolayer) for an experiment lasting for times t≥5 h at a temperature T =300K. Calculate approximately the needed data and calculate a value for the required background pressure in the apparatus if each incident molecule sticks to the surface.
