The Copper Oxide Rectifier

W. H. Brattain1951-07-01Reviews of Modern Physics

It is shown that the conductivity in the ohmic part of the cuprous oxide layer can be explained with the usual band picture of semiconductors only by assuming the presence of some donor-type impurities in addition to the usual acceptor type. The energy difference between the acceptors and the filled band is 0.3 electr…

Quantitative x‐ray studies of order in amorphous and crystalline polymers. Quantitative x‐ray determination of crystallinity in polyethylene

S. Krimm、A. V. Tobolsky1951-07-01Journal of Polymer Science

Abstract Various quantitative scattering relationships for polymers have been examined experimentally in order to test their validity as assumptions in the x‐ray determination of crystallinity. These are ( a ) the proportionality between the scattered intensity and the pt value of the specimen ( p is the density and t…
