Tuning electronic dimensionality with chemistry
An interesting Chemistry of Materials paper illustrates how different types of stacking of organic molecules leads to electronic structures with different dimensionality. This is important in the quest to find Mott insulators with frustrated interactions that are tuned to produce a spin liquid ground state. However, it looks like these materials cannot be described by a half-filled band (there is only a small dimerisation) but rather should be described by a three-quarters filled band.
