Mono-Mono-Mono and Bi-Bi-Bi three-layer graphene systems’ optical conductivity
Investigating the longitudinal optical conductivity of graphene systems, which is the mostimportant property for opto-electronic devices, for three-layer graphene systems theoretically and numerically is the main purpose of this study. Each layer can be mono- or bi-layer graphene. Separation between layers has been denoted by d, selected to be about ten nanometers. The carrier densities i...
متن کاملInvestigating the Longitudinal Optical Conductivity in Three-Layer Graphene Systems with Composes Mono-Bi-Bi and Bi-Mono-Bi and Bi-Bi-Mono
The longitudinal optical conductivity is the most important property for graphene-baseddevices. So investigating this property for spatially separated few-layer graphene systems analytically and numerically is the main purpose of our study. Each layer can be mono- or bi-layer graphene. The density-density correlation function has been screened by the dielectric function using the random p...
متن کاملExtremal Mono-q-polyhexes
A polyhex can be defined as a graph H which is obtained from the hexagonal lattice L6 of the plane by taking a cycle C in the graph of L6 and defining H to be the part of L6 in the disk bounded by C, including C. Similarly, a mono-qpolyhex, q an integer greater than 3, is obtained from the mono-q-hexagonal lattice (all faces are hexagons except one which is a q-gon, and three faces meet at each...
متن کاملSegmentation: mono- or polyphyletic?
Understanding the evolutionary origins of segmented body plans in the metazoa has been a long-standing fascination for scientists. Competing hypotheses explaining the presence of distinct segmented taxa range from the suggestion that all segmentation in the metazoa is homologous to the proposal that segmentation arose independently many times, even within an individual clade or species. A major...
متن کاملMono Regression Benchmarking
Regression benchmarking is a methodology for detecting performance changes in software by periodic benchmarking. Detecting performance regressions in particular helps to improve software quality, similarly as regression testing, which however focuses only on software functionality. To achieve an acceptable level of false alarms, regression benchmarking requires a statistically sound planning an...
