Abstract
Section titled āAbstractāThe outstanding electrical properties of the single crystal chemical vapourdeposition (scCVD) and poly crystal chemical vapour deposition (pcCVD) diamond play an important role for the use of radiation detection. A diamond radiation detector was fabricated using diamond grown on diamond substrate as a basic source material. The detector was tested byOptical Microscope, X-ray diffraction, Raman spectroscopy &(I-V) characteristics. Optical microscope confirms the surface morphology as well as grain boundaries of the diamond films. XRD confirms crystallinity and long range ordered of the film. Raman shows the good content of Sp3 bonds. The measured leakage current was very low ~2.3pA and ~40pA of substrate and grown diamond film and is in good agreement with the reported values by various research groups. The comparison study of silicon, germanium, gallium Arsenide and diamond confirms that diamond isradiation hard than other materials. It causes due to high atomic displacement energy i.e., energy required to displace a carbon atom from its lattice site. Ā© 2019 American Institute of Physics Inc.. All rights reserved.
