"patterned conducting layers with sub-micron insulating gaps in which incident THz field enhanced... created using electron-beam lithography... synthesis of quantum dots and their deposition onto the field enhancement structures... THz-detecting camera detected THz pulses with peak fields as low as 10 kVcm-1 at room temperature, with a fast response rate and high bandwidth. The device is also affordable and can be scaled up to wafer size for large-area imaging or other large-scale applications"
