The films are named due to their high absorbance at visible wavelengths; they appear black to the naked eye. There is a remarkable contrast between such films and films deposited under low pressure (less than $10^{-6}$mbar), which are typically highly reflective and brightly coloured. % First mentions and early research; Pfund @@ -28,3 +39,6 @@ Sondergaard et al. have produced metallic-black surfaces capable of suporting su % 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.
