The physics goals at the future e + e − linear colliders require high performance ver-texing and impact parameter resolution. Two possible technologies for the vertex detector of an experimental apparatus are outlined in the paper: an evolution of the Hybrid Pixel Sensors already used in high energy physics experiments and a new detector concept based on(More)
Phenomena of the radiation coupling to the field effect transistors based terahertz (THz) detectors are studied. We show that in the case of planar metal antennas a significant portion of incoming radiation, instead of being coupled to the transistors, is coupled to an antenna substrate leading to responsivity losses and/or cross-talk effects in the field(More)
This paper summarizes work performed in ITE on development of ionizing radiation detectors integrated on-chip with readout electronics. First, the construction of such detectors will be presented in brief, together with the main features of non-typical silicon process deployed, then the test structures sent for prototyping will be discussed in detail.
Investigations of surface p-i-n (S-PIN) diodes developed for silicon monolithic antennas with reconfigurable aperture have been described. The main criteria for choosing a suitable substrate for the S-PIN diodes have been extensively discussed. Based on this analysis, it has been found that dedicated silicon-on-insulator (SOI) substrates meet the(More)
This paper summarizes work performed within the Polish applied research project THzOnLine aiming at multi-pixel THz detectors based on selective NMOS transistors and its application in biology, medicine and security systems. The techniques applied for increasing the efficiency of THz detectors, as well as issues related to development of the readout(More)
