In his recent measurements of the electrical conductivity of plastically deformed cadmium sulfide, Charles Elbaum of Brown University has found a large anistropy and unusual temperature dependence over a range from 20 to 300 K. The conductivity in the direction of the longest (z) axis of his specimens is from to that along the other two mutually perpendicular directions. As a function of temperature the conductivity along the z axis first rises to a maximum of about near 125 K, then decreases exponentially. By contrast, the conductivities at right angles decrease monotonically from values of about at 300 K to values of about at 125 K. Elbaum feels that the experimental results imply a metallic‐type conduction along a pseudo‐one‐dimensional system consisting of arrays of dislocations.
