While light detection terahertz (THz) frequencies are important for wide range of applications, current detectors are usually a few disadvantages in terms of sensitivity, speed, operating temperature and spectral spectrum. Here we use goggles as photoactive material to move these restrictions on one device. We represent the novel detector terahertz radiation that uses photothermoelectric (PTE) effect, based on a design that employs a dual gated, dipolar antenna with a defect of ~ 100 nm. This narrow-cleaned antenna creates a pn voting simultaneously on the Gramfane channel on the antenna and is strongly concentrated on the pn-separation, where photoresponse is created. We show that this novel detector has excellent sensitivity, noise equivalent power of 80 pW / Response time at room temperature 30 ns (setup-limited), high dynamic range (linear power dependency over 3 on the command line height) and broadband operation (moderate range 1.8-4.2 THz, antenna-limited), which is a combination that is currently missing Is in state level detectors. It is important that on the basis of the agreement we have experimented, analytical model and numerical simulations, we have achieved solid knowledge on how to effect PTE effect for THZ-caused photo reaction, which is very valuable for detective optimization.
