The predictions of the NRL-TB approach for complicated Boron structures such as R105 (or \\b{eta}-rhombohedral) and T190 are in agreement with recent first-principles calculations. Fully utilizing the computational speed of the NRL-TB method we calculated the energetic differences of various structures including those containing vac","authors_text":"Dimitrios A.
