Gallium transport properties

Gallium Phosphide (GaP). Even in high-purity samples, intrinsic conduction occurs in gallium phosphide only above 500 °C. Thus, the transport properties are in general determined by the properties of impurities and lattice defects. The data for the electrical conductivity a of pure n-type material are found to lie around 0.5 cm at 300 K. 

With aqueous solutions in pressurised cells, the temperature can be varied in a very broad range. Many fundamental electrochemical data have been obtained in this medium. Thermodynamic quantities such as activity coefficients of ions [252], equilibrium double-layer capacity [261], zeta potential of metals [233], potential-pH diagrams [206] or properties of the palladium-hydrogen electrode were determined [262]. Exotic systems, e.g. the solvation of rare earth atoms in liquid gallium [234], have been studied. Main research interests in subcritical aqueous solution were focused on the kinetics, reaction mechanism and transport properties.
