Measure of Diracness in two-dimensional semiconductors
M. O. Goerbig, G. Montambaux, F. Piéchon
We analyze the low-energy properties of two-dimensional direct-gap semiconductors, such as for example the transition-metal dichalcogenides MoS, WS, and their diselenide an…
Inversion Symmetry and Wave-Function-Nodal-Lines of Dirac Electrons in Organic Conductor alpha-(BEDT-TTF)_2I_3
Frédéric Piéchon, Yoshikazu Suzumura
By examining organic conductor alpha-(BEDT-TTF)_2I_3 which is described by a nearest neighbors tight-binding model it is shown that because of inversion symmetry, each component of…
Spin- and valley-dependent magneto-optical properties of MoS2
Félix Rose, M. O. Goerbig, Frédéric Piéchon
We investigate the behavior of low-energy electrons in two-dimensional molybdenum disulfide when submitted to an external magnetic field. Highly degenerate Landau levels form in th…
Existence and merging of Dirac points in -(BEDT-TTF)I organic conductor
Frédéric Piéchon, Yoshikazu Suzumura, Takao Morinari
We reexamine the existence and stability conditions of Dirac points between valence and conduction bands of 3/4 filled -(BEDT-TTF)I conducting plane. We consider the usu…
