The Van der Waals and Casimir interactions between graphene and a material plate are studied by using the Lifshitz theory and approximate expressions for the free energy and force. The reflection properties of electromagnetic oscillations on graphene are ... see more

We have analyzed the spin-1/2 isotropic Heisenberg antiferromagnetic system on triangular lattice within Popov--Fedotov functional intergral formalism when the spin operators are represented by the fermionic ones and the constraint of single occupancy con... see more

We present a theoretical study the two-dimensional electron gas (2DEG) at low temperature in an unintentionally doped GaN/AlGaN surface quantum well, taking adequate account of the roughness-induced scattering mechansms and effect due to sheet polarizatio... see more

In 2006, Daniel A. Heller et al. [1] demonstrated that carbon nanotubes (CNNTs) wrapped with DNA can be placed inside living cells and detect trace amounts of harmful contaminants using near infrared light. This discovery could lead to new types of optica... see more

We employ the theory of band-bending effects to explain the channel-width dependence of the mobility of a two-dimentional hole gas (2DHG) in narrow square Si/Si1-x_{1-x}Gex_x/Si quantum well at high Ge content. The numerical calculation of scattering mec... see more

This paper is a brief review of low energy soft hadronic physics,starting from the invention of the low energy effective rangetheory in the late 40's due to Bethe and Schwinger fornucleon-nucleon scattering, and its generalization to the static... see more

In the present study we propose a new method for detectionof high energy cosmological muon neutrinos by transition radiations at amedium interface. The emerging electro-magnetic radiations induced by earth-skimming heavy charged leptons are able to trigge... see more

Photon-axion conversions in the resonant cavity with the mode (TMm10)(\text{TM}_{m10}) are considered in detail. The differential cross-sections and numerical evaluations are presented. It is shown that there is a resonant conversion for the considered pr... see more

The 3C-SiC nanorods were grown by using carbothermal reduction of SiO2_{2} without any catalyst. The intensive broad photoluminescence peak around 480-500 nm was observed at room temperature. The 3C-SiC nanorods with green -- blue emitting light may ha... see more

In this article a two-ports nonlinear fiber Mach-Zehnder interferometer is proposed. The expression for output-input intensity relation and the transmittance function are derived based on principle operation of optical coupler. The expression of coupling ... see more

In this paper, we present the systematically experimental results on the influences of pH of the reaction medium, molar ratio of the precursors on the synthesis in aqueous phase of CdTe quantum dots (QDs) and CdTe/CdS QDs with core/shell structure. Under ... see more
