The anisotropy of the upper critical field of chevrel phase compounds
… in the (001) plane. The data were fit to the effective mass model with uniaxial symmetry. A two-fold symmetry was observed in the Cu1.sMo6S8 in the (2TO) plane. Oscillations with three-fold symmetry have been observed for the first time in the (001) plane. The effective mass model was unable …

Development of spintronics devices and Type 1 heterojunctions from graphene nanoribbon superlattices
… behavior could be predicted from a simple 1D effective mass model, or devices with localized magnetism at the interface sites with potential applications in spintronics. For devices with magnetic interfaces, we show the possibility of forming ferrimagnetic and anti-ferromagnetic materials …

Exciton Dynamics in Perovskite CsPbBr₃ Semiconductor Nanocrystals
… the absorption spectra can be explained with an effective mass model considering the quasicubic NC shape and non-parabolicity of the electronic bands. We observe a temperature-dependent Stokes shift; while the trend is similar to the Stokes shift observed in both MAPbBr₃ and CsPbBr₃ single …

I. Raman scattering and x-ray diffraction study of annealing effects on confined LO and folded LA phonons in GaAs-AlAs superlattices ; II. Picosecond light scattering studies of relaxation and tunneling in GaAs/AlxGa1-xAs mulitple quatum well structures
… doublets, as predicted by the photoelastic model for acoustic phonons in superlattices. We saw downward frequency shifts of confined LO phonons with increasing annealing time. The different annealing effects on frequencies of optical phonons and intensities of acoustic phonons in …

Physical Modeling of Graphene Nanoribbon Field Effect Transistor Using Non-Equilibrium Green Function Approach for Integrated Circuit Design
… materials is still in early stages, transistor modeling has been playing an important role for evaluating futuristic graphene-based devices and circuits. The GNR FET has been simulated by solving a numerical quantum transport model based on self-consistent solution of the 3D Poisson equation and …
