Ab intio calculation of the Transmission Coefficients from a Superlattice electronic structure

نویسنده

چکیده

A new formalism to calculate the transmission coefficient t of electrons from a material L into the same material L through a barrier B is presented. The barrier B is arbitrary and can be metallic, semiconducting or insulating. The important feature of this formalism is that it starts from the electronic structure of a periodic L/B superlattice. The electronic stucture of such a superlattice is calculated selfconsistently within a Screened Korringa-Kohn-Rostoker method. The capability of the new method is demonstrated by means of a free electron model. First results for the transmission of Cu electrons through a Co layer are presented.

The intrinsic defect structure of exfoliated MoS2 single layers revealed by Scanning Tunneling Microscopy

MoS2 single layers have recently emerged as strong competitors of graphene in electronic and optoelectronic device applications due to their intrinsic direct bandgap. However, transport measurements reveal the crucial role of defect-induced electronic states, pointing out the fundamental importance of characterizing their intrinsic defect structure. Transmission Electron Microscopy (TEM) is abl...
