Highly sensitive and tunable terahertz biosensor based on optical Tamm states in graphene-based Bragg reflector
A highly sensitive and tunable biosensor at terahertz (THz) frequencies is proposed by using a composite structure of graphene and one-dimensional photonic crystal. The theoretical analysis and simulation results show that the sensitivity and figure-of-merit of the biosensor can reach 517.9°/RIU and...
