DEVICE AND A METHOD FOR TESTING A QUALITY OF A GRAPHENE SHEET CAPABLE OF ACCURATELY DETECTING DEFECTS ON THE GRAPHENE SHEET

摘要

PURPOSE: A device and a method for testing a quality of a graphene sheet (100) are provided to secondarily perform a precise test using a Raman spectrometer after primarily testing heat distribution, thereby accurately detecting the position and the size of defects generated on the graphene sheet of a large area.;CONSTITUTION: A device for testing a quality of a graphene sheet includes a heat distribution testing device (200), a reading unit (400), and a Raman spectrometer (300). The heat distribution testing device confirms the heat distribution of the graphene sheet. The reading unit determines a defect region based on the obtained heat radiation. The Raman spectrometer emits the laser beams to the defect region when the defect region exists on the graphene sheet and measures Raman spectra of lights scattered from the defect region.;COPYRIGHT KIPO 2013;[Reference numerals] (200) Heat distribution testing device; (210) Current source; (220) Thermal Image camera; (300) Raman spectrometer; (400) Reading unit; (410) Image receiving unit; (420) Control unit; (430) Control unit; (440) Control unit; (450) Detailed defection correcting unit; (460) Location correcting unit
