Thermal regeneration of an adsorptive capacity in oxidized metals and semiconductors is identified with a nonspecific tendency for oxygen atoms to bury themselves. This process, which often occurs at room temperature, leads to a positive surface potential, and the thermionic or photoelectric...
A unified treatment of the mechanics of deformation and acoustic propagation in porous media is presented, and some new results and generalizations are derived. The writer's earlier theory of deformation of porous media derived from general principles of nonequilibrium thermodynamics is applied....
A two‐mechanism model for dislocation damping, which should be valid in the cases of rather dense Cottrell atmospheres, is proposed. The first mechanism arises from the movement of the vibrating dislocation inside the most dense (axial) region of the atmosphere, while the second one, which can...
This article contains experimental reflection and transmission secondary emission yield curves obtained from a 475 Å unbacked MgO film. The film has a transmission yield maximum of 2.6 at a primary energy of 3 kev. An analysis, employing experimental transmission retarding potential...
Irradiation damage of nickel single crystals bombarded with 3 Mev electrons has been studied by Kossel line techniques. Changes of lattice parameter and x‐ray line breadth were determined for crystals bombarded with integrated dosages of 10 16 , 10 17 , and 10 18 electrons∕cm 2 at liquid...
A study has been made of the photovoltaic effect in Au‐CdS and Cu‐CdS photocells in an attempt to determine the origin of the conducting electrons. Evidence is presented to show that, for evaporated films of gold and copper on copper‐doped CdS, the entire photovoltaic current is due to...
