本文报道在填充因子ν = 1/3的范围内，在二维电子系统的真实的对角电导率的微波谱中观察到共振现象。该共振与先前在整数ν附近观察到的共振非常相似，并且被解释为e/3带电载流子的无序钉扎维格纳固相的集体钉扎模式。
We report the observation of a resonance in the microwave spectra of the real diagonal conductivities of a two-dimensional electron system within a range of ∼ ± 0.015 from filling factor ν = 1/3. The resonance is remarkably similar to resonances previously observed near integer ν, and is interpreted as the collective pinning mode of a disorder-pinned Wigner solid phase of e/3-charged carriers.
