Abstract: (1554 Views)
In this paper, graphene containing Se impurity was studied for 4 impurities 2%, 3%, 5.5% and 12.5%. In the absorption spectrum for the ultraviolet range, in three cases, impurities of 2%, 3% and 5.5%, we have two peaks at around 12.58eV and 17.44eV, which can be attributed to graphene. In the case of 12.5% impurity other than the 12.37eV peak, which is similar to other structures, two new peaks arise and the peak of 17.44eV has a significant displacement. In the visible range and around it, cases of 2% and 3% impurities have one peak, and for the 5,5% and 12.5% we see two peaks which can have a variety of applications in optical devices, particularly in visible absorption.
