Abstract

We studied the fully-formed (80 angstroms) Pt/GaP and (140 angstroms) Au/GaAs interfaces by scanning near-field optics microscopy, internal photoemission, atomic force microscopy, and by x-ray photoemission electron microscopy. These complementary techniques enabled us to correlate the spatial variations of the diodes transport properties with the chemical and topographic inhomogeneities of the buried metal-semiconductor interfaces.© (1996) COPYRIGHT SPIE--The International Society for Optical Engineering.

Abstract

We present several experimental results of imaging DNA on graphite. Images have been taken simultaneously in constant-current and gap-modulated mode. This way of imaging has been very helpful in order to discriminate between structures due to biological molecules and substrate artifacts. A possible way of using the tip to confirm this conclusion is shown.© (1993) COPYRIGHT SPIE--The International Society for Optical Engineering.
