- W2556807577 abstract "We have measured absorption and velocity of surface acoustic waves (SAWs) in high-mobility samples n-GaAs/AlGaAs in magnetic fields (12–18) T (filling factors ν = 0.18–0.125) at temperatures T = (40–340) K and SAW frequencies f = (30–300) MHz. From the measurement data, the complex AC conductance, σAC(ω) ≡ σ1(ω)—iσ2(ω) and its dependences on frequency, temperature, and the amplitude of the SAW-induced electric field were found. We conclude that in the studied interval of the magnetic field and at T < 200 mK, the electronic systems forms pinned Wigner crystal, the so-called Wigner glass. The estimate of the correlation (Larkin) length of the Wigner glass is about 3 μm, which is much larger than both the distance between the electrons and the magnetic length in the studied field range. At some temperature Tm, the temperature dependences of both components of the complex conductance get substantially changed: from the dielectric behavior at T < Tm to the metallic one at T > Tm. We ascribed this change of the conduction mechanism to melting of the Wigner crystal and studied the dependence of the so-defined melting temperature on the electron filling factor.
