Molecular thin films utilizing phosphonates are widely used in a variety of chemical applications, such as surfactants, stabilization of nanoparticle suspensions, layer by layer film formation, and more. Furthermore, surface chemistry is a valuable tool in the context of semiconducting materials. To date, the studies of monolayer formation of phosphonates have mainly focused on phosphonic acids...

Unprecedented and fascinating phenomena have been recently observed at oxide interfaces between centrosymmetric cubic materials, where polar discontinuities can give rise to polarization charges and electric fields that drive a metal-insulator transition and the appearance of a two-dimensional electron gas. Lower-dimensional analogues are possible, and honeycomb lattices offer a fertile playgro...
