Twisted bilayer blue phosphorene: A direct band gap semiconductor
We report that two rotated layers of blue phosphorene behave as a direct band gap semiconductor. The optical spectrum shows absorption peaks in the visible region of the spectrum and in addition the energy of these peaks ...
Effects of external electric field on the optical and electronic properties of blue phosphorene nanoribbons: A DFT study
Using first principles calculations we investigate the effect of external electric fields in the optical and electronic properties of blue-phosphorene nanoribbons. It is shown that the application of a static external ...
