摘要：

In this work graphitic structures were fabricated on high quality polycrystalline CVD diamond by using a UV laser beam (lambda = 193 nm). Two different kinds of structures were realized on diamond to study the evolution from diamond to graphite at different irradiation conditions (spot like structures) and to study their electrical transport properties (strip like structures). The graphitic structures were characterized structurally and morphologically by micro-Raman spectroscopy and atomic force microscopy. The electrical properties were evaluated using the transmission line model. Finally, a full carbon detector was built and tested showing good nuclear detection properties. (C) 2016 Elsevier B.V.
