A Direct Determination of an Upper Limit for the Electrical Charge on Dislocations in Ice
Abstract A direct determination of the upper limit for the electric charge density along dislocations in ice has been carried out by measuring the simultaneous effects of an electric field and a mechanical stress on the movement of a low-angle tilt boundary in an ice single crystal. The determinatio...
