An unusual rectangular-based droplet shape is identified and the contact angle is determined in situ. It is shown that quenching does not appreciably affect droplet shape and ex situ measurements of the contact angle by atomic force microscopy are in good agreement with Lloyd's mirror PEEM. Extension of Lloyd's mirror technique to reconstruct general three-dimensional (3D) surface shapes and the potential use of synchrotron radiation to improve vertical resolution is discussed. | Publication Type: | Journal Article | Source of Publication: | Journal of Physics: Condensed Matter, 21(31), p. 1-5 | Publisher: | Institute of Physics Publishing Ltd | Place of Publication: | United Kingdom | ISSN: | 1361-648X 0953-8984 |
