We study the optical response of multilayer graphene quantum dots at THz frequencies. We fabricate 73 nm diameter graphene quantum dots in an array of ~1mm 2 size. We demonstrate optical absorbance of these graphene quantum dots from 0.85 to 4.7 THz and study the absorption dependence with the temperature from 4K to 300 K.
