  title = {Trends in the electronic structure of borophene polymorphs},
  abstract = {<p>Borophene is a two-dimensional material made out of boron atoms only. It exhibits polymorphism<br>and different allotropes can be studied in terms of a rigid electronic structure, where only the<br>occupation of the states change with the respect to the number of electrons available in the system<br>(self-doping). In this work we selected a set of representative borophene polymorphs (δ3 , δ5 , δ6 , β12<br>α1 , α′ , α′ -Bilayer) and studied the shared features of their electronic structures and the limitations<br>of this model. Our work revealed the appearance of defect-like states in some polymorphs when<br>related to a parent rigid electronic structure, and bonding/antibonding monolayer-like states in<br>the α′ -Bilayer. Moreover, we show how the buckling of δ6 and α′ can act as a tuning parameter,<br>enabling semimetallicity, Dirac cones, and nesting of the Fermi surface. In light of their promises<br>for exotic but also useful behavior, we expect our work to foster the interest in larger and more<br>complex borophene structures.</p>},
