The surface topography of the CVD diamond layers was investigated using atomic force microscopy (AFM), and Kelvin probe force microscopy (KPFM) was employed to measure the contact potential difference (CPD) to calculate the work function of these CVD diamond layers.*<\/p>\n
Atomic force microscopy topography depicted the flat and smooth surface with low surface roughness for low B doping, whereas surface features like hillock structures and un-epitaxial diamond crystals with high surface roughness were observed for high B doping concentrations. KPFM measurements revealed that the work function (4.74\u20134.94 eV) has not varied significantly for CVD diamond synthesized with different B\/C concentrations.*<\/p>\n
