Transport properties of cubicNaxWO3near the insulator-metal transition

Abstract

We have extended previous measurements of electrical resistivity and Hall coefficient of single crystals of cubic ${\mathrm{Na}}_x\mathrm{W}{\mathrm{O}}_3$ to a wider range of values of $x$ and of sample temperature. These new data cover a temperature range from 4.2 to 300 K, and a range of $x$ values from $x=0.22\mathrm{} \mathrm{to} 0.30$.
