-% More recent research
-More recently, it was shown that Au-black coatings increased the efficiency of thin film solar cells \cite{}. In this study, a simulation approximating an Au-black film as a layer of semi-spherical structures showed plasmonic behaviour which lead to an increase in electric field behind the film.

-% Artificially ``blackened'' thin films
-Metallic-black films have proven useful in applications requiring efficient absorption of light, including the. Recently there has been interest in artificial ``blackening'' of metal surfaces in ways which simplify the characterisation of the surfaces for practical applications.
-
-Sondergaard et al. have produced metallic-black surfaces capable of suporting surface plasmon modes \cite{sondergaard2012}. These films exhibit similar optical properties to the previously considered ``evaporated'' metallic-black surfaces.

-% What I will be doing with metallic-black films
-This project will employ several techniques, including:Total Current Specroscopy; Ellipsometry and Optical Spectroscopy to investigate the difference between metallic films deposited at low pressure, and high pressure (metallic-blacks).
-
-This report will be organised as follows...
-You just read the introduction, which comes first. After that we talk about theory and then experimental stuff.
+\subsubsection*{A Note on Terminology}
+There is some possibility for confusion when referring to metal films evaporated at high pressure, which appear black at visible wavelengths, and metal films evaporated at low pressure, which are typically highly reflective. In the remainder of this report, we will refer to the former as ``black metal'' films and the latter simply as ``metal'' films (regardless of whether the film is thick enough for the colour to be visible to the naked eye).
