Abstract

In semi- or superconducting compounds, with a relatively mobile component, this component's local concentration can be varied significantly by ion electromigration that occurs while the bulk of the material remains at or below room temperature. Because in ABX₂ semiconductors (with A = Cu or Ag, B = In or Ga and X = S, Se or Te) or in (Hg,Cd)Te changing the concentration of the mobile Cu, Ag or Hg(?) affects their electrical properties (via control of the electronic carrier density), this allows for actual room temperature device creation. In high T_c cuprate superconductors oxygen is mobile and its local concentration can be changed electrochemically at room temperature to control T_c and other electronic properties.
