Genuine two-dimensional electrons have been realized in the Bechgaard salt, the representative quasi-one-dimensional electron system. Two-dimensional characteristics such as Yamaji resonance, conventional magnetic quantum oscillations, a coherent interlayer magnetoresistance peak effect, and so on were clearly observed in tetramethyltetraselenafulvalene fluorosulfonate (TMTSF)2FSO3, a unique example that has anions with finite electric dipole moments. The introduction of additional periodic potential due to electric dipole moments drastically changes the electronic structure.
