Abstract

The surface modifications that occur on °-mercuric iodide surfaces during the fabrication process are crucial for the development of a low noise, high resolution X-ray spectrometer. In this study, we discuss the effects of surface treatments on the dark currents and the results are correlated with surface morphology studies that were carried out by the atomic force microscopy (AFM) technique.
