By probing the low-disorder two-dimensional electron system at submicron dimensions, important new length scales are revealed. Using surface acoustic waves of wavelength )~ < 1 gm to measure the 2D electron conductivity, enhanced conductivity is observed at even-denominator filling factors v = Β½, ΒΌ:
