Abstract :
Zero-bias detectors based on low-barrier Schottky diodes and planar slot antennas are investigated at 94 GHz. Diodes with differential contact resistances Rj =1+1000 kOmega at zero bias are used. The better voltage responsivity - more than 10000 V/W - is obtained at Rj =20+100 kOmega. At lower values of Rj =2+6 kOmega a better noise equivalent power NEPap10-12 WmiddotHz-1/2, is observed. Experimental data are compared with the simulation in a simple model of detector.
