- W1616841739 abstract "We present zero magnetic-field resistivity measurements of the variable-range hopping (VRH) in a two-dimensional electron gas created at a ensuremath{delta}-doped $mathrm{GaAs}/{mathrm{Al}}_{x}{mathrm{Ga}}_{1ensuremath{-}x}mathrm{As}$ heterostructure. When either the temperature or carrier density are reduced the longitudinal resistivity shows a crossover from two-dimensional Mott VRH, $ensuremath{rho}(T)={ensuremath{rho}}_{M}mathrm{exp}{(T}_{M}{/T)}^{1/3}$ to Efros-Shklovskii (ES) Coulomb-gap behavior $ensuremath{rho}(T)={ensuremath{rho}}_{mathrm{ES}}mathrm{exp}{(T}_{mathrm{ES}}{/T)}^{1/2}.$ In both regimes, near the crossover, the data collapse onto universal curves with a temperature independent prefactor ${ensuremath{rho}}_{M}ensuremath{approx}{(1/2)(h/e}^{2})$ or ${ensuremath{rho}}_{mathrm{ES}}ensuremath{approx}{h/e}^{2}.$ The latter result is in close agreement with measurements of Si metal-oxide-semiconductor field-effect transistors. We discuss the possible implications of our data on the theory of phonon-assisted VRH." @default.
