S. Bogdanovich et al., Scaling of the conductivity with temperature and uniaxial stress in Si : Bat the metal-insulator transition, PHYS REV L, 82(1), 1999, pp. 137-140
Using uniaxial stress S to tune Si:B through the metal-insulator transition
at a critical value S-c, we find the de conductivity at low temperatures s
hows an excellent fit to the scaling form sigma(S, T) = AT(x) f[(S - S-c)/T
-y] on both sides of the transition. The scaling functions yield reliable d
eterminations of the temperature dependence of the conductivity in the meta
llic and insulating phases in the critical region. [S0031-9007(98)08115-0].
