A study of the physics of electronic states in cubic InAs quantum dot periodic nanostructures embedded in GaAs is presented. The miniband structure of electron states in the conduction band is related to the size and density of the quantum dots. The effect of strain is also taken into account in the simulations. The photon-electron absorption coefficient is obtained for different quantum dot configurations...
The electronic behavior of organic molecules, which could be considered as basic blocks of graphene nanoribbons, has been studied using Density Functional Theory and Non-Equilibrium Green Functions approaches. We have focused on the role that plays the molecule-metal contact, for this reason different configurations in the number and position of the contacts have been considered. We have noticed that...
In this work we have studied the electronic behavior of organic molecules that could be considered as basic blocks of graphene nanoribbons. We have focused on the role that plays the molecule-metal contact. Thus, the influence of the number and positions of those contacts is analyzed. To carry out the calculation we have used the Density Functional Theory and Non-Equilibrium Green Functions Approach.
