Abstract: We investigate theoretically the response mechanism in Ge:Ga-photo detectors and conclude that only very thin detector elements with thickness of the order 0.1 mm or less obtain reasonably bandwidth of the order of 50 MHz and higher.

Keywords: THz-detector 118.9 µm wavelength, Ge:Ga-detector, Fast response.
