Abstract

We report the terahertz photoconductivity in a meander-shaped epitaxial graphene sample. The measurements at wavelengths 280, 148, and 90 mu m (frequencies of 1.07, 2.03, and 3.32 THz) demonstrate that the photoconductivity is independent on the wavelength and is related to bolometric heating under the condition of weak localization enhanced due to long sample boundaries.
