Blue phosphorene bilayer is a two-dimensional metal -- and an unambiguous classification scheme for buckled hexagonal bilayers
Jessica Arcudia, Roman Kempt, Miguel Eduardo Cifuentes-Quintal +2
High-level first-principles computations predict blue phosphorene bilayer to be a two-dimensional metal. This structure has not been considered before and was identified by employi…

Two dimensional crystals in three dimensions: electronic decoupling of single-layered platelets in colloidal nanoparticles
Roman Kempt, Agnieszka Kuc, Jae Hyo Han +2
Two-dimensional crystals, single sheets of layered materials, often show distinct properties desired for optoelectronic applications, such as larger and direct band gaps, valley- a…
