Ok , thak you!
I pose this question because I'm working on graphene photodetectors. Graphene exhibits a flat absorbance over a wide range of optical frequencies. There are some experiments that show this, for example http://arxiv.org/ftp/arxiv/papers/0810/0810.1269.pdf. In this work they...
Hello everybody,
I'm new. It's a long time a have a big (probably stupid) doubt about the interaction between light and media, and now it's time to solve it. The doubt its essentially concerning the difference between an antenna and a photodetector: the first one is able to detect the amplitude...
