Electron Beam Effects In The Analysis Of Compound Semiconductors And Devices, Nancy Burnham, Ll Kazmerski, Ab Swartzlander, Aj Nelson, Se Asher

Nancy A. Burnham

The effects of electron beams on the analysis of CuInSe2surfaces are examined in this paper. Potential changes in the surface chemistry—including oxidation and desorption—under a range of incident probe conditions, are investigated for possible artifactual information generation. Emphasis is placed on the relationships between beam conditions and oxygen chemisorption and physisorption, since oxygen treatments of devices utilizing this semiconductor are critical to performance. Single crystals and polycrystalline thin films are analyzed and compared to establish the beam‐induced phenomena.

Electrochemical Reduction Of 1,1,4,4-Tetraphenylbutatriene, Tsu-Yu Chen, Mark Anderson, Dennis Peters

Mark R. Anderson

Polarograms and cyclic voltammograms for reduction of 1,1,4,4-tetraphenylbutatriene at mercury electrodes in dimethylformamide containing tetra-n-butylammonium perchlorate exhibit four waves; the first and second waves are due to stepwise formation of the radical anion and dianion of the starting material, whereas the third and fourth waves are attributable to reduction of 1,1,4,4-tetraphenyl-1,2-butadiene and 1,1,4,4-tetraphenyl-1-butene, respectively. Electrolysis of 1,1,4,4-tetraphenylbutatriene at potentials corresponding to the second wave yields 1,1,4,4-tetraphenyl-1,3-butadiene exclusively; at a slightly more negative potential, the latter undergoes reduction to 1,1,4,4-tetraphenyl-1-butene. When 1,1,4,4-tetraphenylbutatriene is electrolyzed in the presence of glacial acetic acid and at any potential on the first or second wave, …

Electrochemical Reduction Of Phenylpropadiene At Mercury Cathodes In Dimethylformamide: Isomerization Of The Allene To 1-Phenyl-1-Propyne, Tsu-Yu Chen, Mark Anderson, Steven Grossman, Dennis Peters

Mark R. Anderson

Polarograms and cyclic voltammograms exhibit two waves for reduction of phenylpropadiene at a mercury electrode in dimethylformamide containing tetra-n-butylammonium perchlorate, the f i t wave signals reduction of phenylpropadiene to 1-phenyl-1-propene and the second wave is attributable to reduction of 1-phenyl-1-propene to 1-phenylpropane. However, the fmt wave is abnormally small because phenylpropadiene undergoes substantial rearrangement to 1-phenyl-1-propyne, which is reducible to 1-phenylpropane at nearly the same potential as 1-phenyl-1-propene. Controlled-potential electrolyses of phenylpropadiene, 1-phenyl-1-propene, and 1-phenyl-1-propyne at mercury pool cathodes have verified the processes elucidated by means of polarography and cyclic voltammetry. In the presence of diethyl malonate (a proton …

Kobayashi-Maskawa Angles And Su(3) Breaking In Hyperon Beta-Decay, Jf Donoghue, Br Holstein, Sw Klimt

Barry R Holstein

The determination of the Kobayashi-Maskawa matrix element Vus from hyperon β decays has long had a hidden uncertainty due to the almost universal assumption of SU(3) invariance in Cabibbo-type fits, especially since the data definitely indicate the presence of SU(3) breaking. We have reanalyzed the hyperon-decay data using the pattern of symmetry breaking predicted by the quark model including the center-of-mass correction. We find that the SU(3)-broken picture is far superior to the assumption of perfect SU(3), and provides a good fit to experiment. The sensitivity of Vus to the breaking is not large and we find Vus=0.220+/-0.001+/-0.003 (the errors …

Implications Of Atmospheric Test Fallout Data For Nuclear Winter, George H. Baker

George H Baker

Atmospheric test fallout data have been used to determine admissible dust particle size distributions for nuclear winter and nuclear fallout studies. The research was originally motivated by extreme differences noted in the magnitude and longevity of dust effects predicted by particle size distributions routinely used in fallout predictions versus those used for nuclear winter studies. Three different sets of historical data have been analyzed:

1. Stratospheric burden of Strontium-90 and Tungsten-185, 1954-1967 (97 contributing events) 2. Continental U.S Strontium-90 fallout through 1958 (75 contributing events) 3. Local Fallout from selected Nevada tests (16 events)

The contribution of dust to possible …

Dedekind Finiteness In Topoi, Lawrence Stout

Lawrence N. Stout

A Dedekind finite object in a topos is an object such that any monic endomorphism is an epimorphism. This paper proves the basic properties of Dedekind finiteness and then gives examples which show that the class of Dedekind finite objects is not closed under quotients, subobjects, exponentiation, or finite powerobjects. Examples also show that having no nontrivial epic endomorphisms is distinct from Dedekind finiteness.
