Question
An ablation plume is formed by a pulsed laser in one technique named for this process. For 10 points each:
[10m] Name this process observed in electroplating. The occurrence of decomposition near a surface before absorption differentiates the “chemical vapor” and “physical vapor” forms of techniques employing this process.
ANSWER: deposition [accept physical vapor deposition or chemical vapor deposition; accept pulsed laser deposition; accept electrodeposition; prompt on PVD or CVD or PLD; antiprompt on molecular beam epitaxy]
[10e] Copper foils are often used as the substrate for the chemical vapor deposition of this material, a single-layered allotrope of carbon.
ANSWER: graphene [reject “graphite”]
[10h] One kind of physical vapor deposition employs this technique to apply an antireflective coating onto lenses. This technique, itself a form of physical vapor deposition, involves bombarding incident ions onto a source material.
ANSWER: sputtering [or sputter deposition; accept resputtering]
