We present direct measurements of the ultrafast carrier dynamics around buried nano-scale Schottky contacts with high spatial and time resolution, performed with a novel femtosecond near-ÿeld scanning optical microscope. It is shown that high optically excited carrier densities screen the built-in ÿ
