These arrays use infrared photovoltaic detectors coupled to a silicon readout circuit. This paper gives some new experimental results obtained with arrays of Pb0.80Sn0.20Te detectors (10.6µm cutoff wavelength) coupled to a silicon CCD. For electrical coupling the direct injection mode is used, in which the photocurrent from each detector is injected into the CCD through an input diffusion. The signal efficiency is measured and the noise sources of the CCD readout are determined : detector noise, coupling noise and transfer noise in the CCD channel. The performances of this readout and its main limitations are analyzed. Experimental results are also given for a hybrid mosaic of 10 × 10 Pb0.80Sn0.20Te infrared detectors on a silicon CCD readout circuit. For this small staring array, batch technology is used to obtain an \"island\" structure that is compatible with the mismatch of the thermal-expansion coefficients of lead salt and silicon. The effects of threshold voltage dispersion and of the transconductance figure of the CCD are discussed in relation to the characteristics of the detectors. Signal and noise homogeneities measured on the array are also discussed.","PeriodicalId":180541,"journal":{"name":"1980 International Electron Devices Meeting","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133783524","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We report the results of experimental and theoretical study of ballistic and near ballistic electron transport in the [100] direction in submicron GaAs layers grown by MBE. Results obtained from I-V measurements and magnetoresistance studies are interpreted in conjunction with the predictions of theoretical models to show that high values of drift velocity and large mean free path lengths are reached in short GaAs structures.","PeriodicalId":180541,"journal":{"name":"1980 International Electron Devices Meeting","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130601942","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For instance, the replacement of Klystrons by a combination of solid state sources plus frequency multipliers at millimeter wavelengths has a strict LO power requirement. The barrier height φBis the important diode parameter in that it determines the local oscillator power required to bias the Schottky diode into its non-linear region. Schottky barriers to InP exhibit a low barrier due to the fact that the Fermi level is not pinned in the center of the energy gap. However, the development of reliable Schottky barriers to InP has been hampered by the large leakage current Schottky barriers to InP have exhibited. In the present paper, we report on a low barrier height, low leakage current Schottky barrier to InP. The InP Schottky barrier diodes fabricated have exhibited low noise figure at 36 and 94 GHz and require exceptionally low local oscillator power. The metallization scheme consisted of TiW sputtered at 200 W rf power. These diodes were processed with a 5 µm diameter active area on n-n+InP layers. At 36 GHz a noise figure of 6.5-7.0 dB resulted at LO power of .5 mW. At 94 GHz the noise figure of 8.0 dB required a LO power of only 0.75 mW.","PeriodicalId":180541,"journal":{"name":"1980 International Electron Devices Meeting","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116672332","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This high power millimeter wave amplifier is designed specifically for a coherent millimeter wave radar which is being designed and constructed by Massachusetts Institute of Technology, Lincoln Laboratory, under the sponsorship of the US Army Ballistic Missile Defense Advanced Technology Center. The amplifier was operated at beam voltage of 46.5 kilovolts with a beam current of 4.0 amperes. The tube requirements were 30 kilowatts peak, 3 kilowatts average over 1000 megahertz, 1 dB bandwidth, at a center frequency of 35 gigahertz with 50 dB saturated gain. These requirements were achieved during the development program with 17 percent interaction efficiency. The paper will describe the design concepts used in the development of this milimeter wave TWT amplifier. Design of the electron beam system, which is considered the highest power density electron beam generated to date, and the unique coupled cavity circuit design will be discussed in some detail. Test data for both the beam system and r.f. circuit will be presented. The r.f. performance characteristics of the tube will also be discussed and measured data presented.","PeriodicalId":180541,"journal":{"name":"1980 International Electron Devices Meeting","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123812204","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
