  • 1/f-noise prediction in millimeter wave detectors based on quasi vertical Schottky diodes 
    HOEFLE, Matthias; PENIRSCHKE, Andreas; COJOCARI, Oleg; AMRHEIN, Andreas; DECOOPMAN, Thibaut; PIIRONEN, Petri; JAKOBY, Rolf (IEEE, 2013)
    A modeling concept for accurate prediction of 1/f-noise in millimeter wave Schottky detectors is presented. The concept is based on DC bias current measurements with precise knowledge of the diode structure. Key aspect is ...
  • 89 GHz zero-bias Schottky detector for direct detection radiometry in European satellite programme MetOp-SG 
    HOEFLE, M.; PENIRSCHKE, A.; COJOCARI, O.; DECOOPMAN, T.; TRIER, M.; PIIRONEN, P.; PÉRICHAUD, M. G.; JAKOBY, R. (The Institution of Engineering and Technology, 2014)
    An 89 GHz waveguide coupled direct detector based on a low-barrier Schottky diode is presented. The main focus is to reduce white and 1/f noise to achieve high signal-to-noise ratio values above 35 dB. The design also ...
  • Compact quasi-optical Schottky detector with fast voltage response 
    PENIRSCHKE, A.; SOBORNYTSKYY, M.; PREU, S.; MITTENDORFF, M.; WINNERL, S.; HOEFLE, M.; COJOCARI, O.; JAKOBY, R. (IEEE, 2014)
    Zero-bias Schottky diode detectors operated at room-temperature are the choice for applications, where the ultimate sensitivity of a cryogenic detector is not needed. Furthermore Schottky detectors are intrinsically much ...
  • Highly responsive planar millimeter wave zero-bias Schottky detector with impedance matched folded dipole antenna 
    HOEFLE, M.; HAEHNSEN, K.; OPREA, I.; COJOCARI, O.; PENIRSCHKE, A.; JAKOBY, R. (IEEE, 2013)
    A compact highly responsive planar zero-bias Schottky detector is proposed for uni-planar and low-cost fabrication. Various zero-bias Schottky diodes are investigated, in particular the optimization of impedance matching ...
  • Optical mixing in THz Schottky diodes 
    SCHOENHERR, D.; COJOCARI, O.; SYDLO, C.; GOEBEL, T.; FEIGINOV, M.; HARTNAGEL, H. L.; MEISSNER, P. (IEEE, 2008)
    This paper presents the effect of optical mixing in zero-bias InGaAs Schottky detectors at THz frequencies. The excitation of ultrafast carriers by illumination with two 1.5 mum laser beams is verified. This proves the ...
  • Qualification of Direct Detection Technology for ESA MetOp-SG Space Mission 
    HOEFLE, Matthias; RICKES, Martin; OPREA, Ion; COJOCARI, Oleg (International Symposium on Space Terahertz Technology, ISSTT, 2017)
    This contribution presents the ACST 89 GHz Schottky detector module performance and pre-qualification results towards the second European meteorological operational satellite program MetOp-SG. The detector flight module ...
  • THz Electronics 
    FEIGINOV, Michael; GONZALO, Ramón; MAESTROJUÁN, Itziar; COJOCARI, Oleg; HOEFLE, Matthias; LIMITI, Ernesto (John Wiley & Sons, Ltd, 2005)
    Summary Several key topics in THz electronics are discussed. We describe the operating principles, limitations, and state-of-the-art of resonant-tunnelling diodes (RTDs) and THz RTD oscillators. Furthermore, THz fundamental ...
