This figure illustrates the Signal-to-Noise Ratio (SNR) for both normal terracotta amplifiers and graphene-based terracotta amplifiers. The red color indicates the SNR values for the graphene-based terracotta amplifier, while the green color represents the SNR values for the normal terracotta amplifier. The comparison highlights the performance differences between the two types of amplifiers, representing the potential improvements achieved with graphene integration.
