Sample in ARPES

Caption

Sample imaged using ARPES: Scientists at PGI-3 used angle-resolved photoelectron spectroscopy (ARPES) to determine the degree of doping in the graphene samples. For this method, the samples are irradiated with UV light to detach electrons from the materials. The electrons can then be detected. The original bond energy of the detached electrons determines the velocity at which they hit the detector. In this way, the scientists were able to reconstruct the band structure of the graphene.
