Metal-insulator transitions
Research on metal–insulator transitions is at the moment quite fashionable. In many materials the electrical behavior changes from metallic to nonmetallic when the pressure, temperature or magneticExpand

  • 1 April 1989
Abstract If the distance between atoms in a crystalline lattice is increased, an energy gap appears, which in a divalent material will separate occupied from unoccupied states of an electron. In aExpand
Metal-Insulator Transition
A general survey of the idea of the metal-nonmetal transition is given with particular emphasis to the following points: (a) is the transition of first order; (b) can one observe the transition; andExpand
The theory of indentation and hardness tests
A discussion is given of the indentation of ductile materials by cylindrical punches with conical heads. On the experimental side, experiments have been made with work-hardened and with annealedExpand

  • 1 December 1968
Abstract In a discussion of conduction in glasses containing transition metal ions, the following points are stressed: 1. (a) The process is similar to “impurity conduction” in doped and compensatedExpand
Polarons in crystalline and non-crystalline materials
The current state of polaron theory as applicable to transition metal oxides is reviewed, including problems such as impurity conduction where disorder plays a role. An estimate is given of theExpand
The Basis of the Electron Theory of Metals, with Special Reference to the Transition Metals
It is shown that the collective electron and London-Heitler models are not to be regarded as different approximations to the same exact wave function for solids in which, according to the formerExpand

  • 1 February 1936
1— In a recent paper certain property of the transition metals Ni, Pd, and Pt and of their alloys with Cu, Ag, and Au have been discussed from the point of view of the electron theory of metals basedExpand
Conduction in non-crystalline systems V. Conductivity, optical absorption and photoconductivity in amorphous semiconductors
Abstract The experimental evidence concerning the density of states in amorphous semiconductors and the ranges of energy in which states are localized is reviewed; this includes d.c. and a.c.Expand
