Answer 2

Explanation:

In spots where the gold is two atomic layers thick, exactly the opposite – p-doping – happens. There, missing electrons or positively charged so-called “holes” act as charge carriers. The gold also enhances the interaction of plasmons (i.e. fluctuations in the density of charge carriers) with electromagnetic radiation
