Untitled
Using ab initio calculations we have studied the optical linear response of different configurations of twisted trilayer graphene systems. We have found that when one of the outer layers is rotated the system shows an ...
Untitled
We have observed by means of scanning tunneling microscopy (STM) moiré patterns corresponding to the rotation of one graphene layer on HOPG surface. These moiré patterns were characterized by rotation angle and extension ...
Untitled
The stability, electronic and optical properties of single-walled carbon nanotubes (CNTs) and graphene noncovalently functionalized with free-base tetraphenylporphyrin (TPP) molecules is addressed by density functional ...
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 ...
