Abstract

Non-bolometric detection is observed in granular superconducting NbN films. Detection, related to the non-linear I-V's, occures over a large bias range. Preliminary results give a sensitivity of 20 V/W and NEP of 5×10−6W at 4 K. Granular NbN films show no apparent degradation with time.

Submillimeter detector operation of granular superconducting NbN films

G. L. Carr, David R. Karecki, Sidney Perkowitz

Detection of submillimeter radiation between 10 and 40 cm−1 (300–1200 GHz) has been carried out with a high resistance granular NbN film (R⧠= 8440 Ω/⧠) below 6 K with evidence of Josephson-like operation. The nonoptimized detector sensitivity and noise equivalent power at 17.5 cm−1 (525 GHz) were about 20 V/W and 5×10−8 W/Hz1/2, respectively, comparable to values obtained with granular Sn and Pb.

Microwave detection using granular Bi-Sr-Ca-Cu-O thin films

Bradley G. Boone, Raymond M. Sova, K. Moorjani +2 more

We report here results of our investigations of the nonbolometric mode of detection in granular Bi-Sr-Ca-Cu-O thin films. We find that both bolometric and nonbolometric modes appear in the same sample under mutually exclusive conditions: bolometric with light (633 nm) and nonbolometric with microwaves (9 GHz). Our measurements indicate that the nonbolometric mode of detection is more sensitive than the bolometric mode in our samples, a result which offers promise for application to microwave power measurement. Possible mechanisms for the nonbolometric mode are reviewed, and the concept of using a broadband spiral antenna directly coupled to the superconducting detector for microwave power sensing is briefly described.

Broadband ultrafast superconducting NbN detector for electromagnetic radiation

Yu. P. Gousev, Gregory N Gol'tsman, A. D. Semenov +4 more

An ultrafast detector that is sensitive to radiation in a broad spectral range from submillimeter waves to visible light is reported. It consists of a structured NbN thin film cooled to a temperature below Tc (∼11 K). Using 20 ps pulses of a GaAs laser, we observed signal pulses with both rise and decay time of about 50 ps. From the analysis of a mixing experiment with submillimeter radiation we estimate an intrinsic response time of the detector of ∼12 ps. The sensitivity was found to be similar for the near-infrared and submillimeter radiation. Broadband sensitivity and short response time are attributed to a quasiparticle heating effect.

Nonbolometric NbN photodetector

Mark W. Johnson, A.M. Domino, Alan M. Kadin

There have been several recent reports of apparently nonbolometric optical responses in superconducting thin films. The photoresponse of 10 nm thin superconducting NbN meander lines on Si is measured at 670 nm using a diode laser modulated to more than 100 kHz. Several types of photoresponse are identified, some apparently due to the Si substrate. A fast photoresponse due to the NbN film with a responsivity of up to 125 V/W of absorbed power was observed. Results are analyzed in the context of a bolometric model, and the magnitude of the photoresponse is found to be too large for a purely bolometric response. Possible nonbolometric alternatives are discussed.>

Use of granular NbN as a superconducting bolometer

Kurt Weiser, Ulrich Strom, S. A. Wolf +1 more

An ultrathin film of granular NbN is used as a superconducting bolometer. The bolometer has a high operating temperature (∼12 K), is very sensitive (∼5000 Ω/deg), and exhibits a fast thermal response time, which is estimated to be less than 10−10 sec.

Superconductive bolometers for submillimeter wavelengths

John L. Clarke, G. I. Hoffer, P. L. Richards +1 more

Three types of composite superconductive bolometers are described in which the temperature-sensitive element is a superconducting film at the transition temperature, a superconductor–normal metal–superconductor Josephson junction, or a superconductor–insulator–normal metal quasiparticle tunneling junction. The temperature-sensitive element is evaporated onto a sapphire substrate on the reverse side of which is a bismuth film to absorb the submillimeter radiation. The noise limitations of each type of bolometer are calculated. The fabrication and measured performance of the transition-edge bolometer and the Josephson-junction bolometer are described. The best electrical (noise-equivalent power) NEP obtained with a transition-edge bolometer fabricated on a 4×4×0.005-mm sapphire substrate is (1.7±0.1) ×10−15 W Hz−1/2 at 2 Hz at an operating temperature of 1.27 K. This NEP is within a factor of 2 of the thermal noise limit. The effective absorptivity of the bismuth film is measured to be 0.47±0.05, and the corresponding detectivity D* is calculated to be (1.1±0.1) ×1014 cm W−1 Hz1/2. Suggestions are made for further improvements in sensitivity.
