An idealized design of a silicon betavoltaic battery with a tritium source is considered, in which a thin layer of tritiated silicon is sandwiched between two intrinsic silicon slabs of equal width, and the excess charge carriers are collected by thin interdigitated n+ and p+ electrodes. The opposite sides of the device are covered with a reflectin...

The general potential of power-law inflation is as V (ϕ) ∝ ϕn with scalar field ϕ. The behavior of inflation is often known as power-law expansion like S(η) ∝ η1+β with 1 + β < 0. In this paper, the theoretical spectra of relic gravitational waves are compared with the measured strain sensitivity of Advanced LIGO and VIRGO, corresponding to the lat...

The general potential of power-law inflation is as $ V(\phi)\propto \phi^{n} $ with scalar field $\phi$. The behavior of inflation is often known as power-law expansion like $S(\eta)\propto \eta^{1+\beta}$ with $1+\beta<0$. In this paper, the theoretical spectra of relic gravitational waves are compared with the measured strain sensitivity of Advan...

The structural, electronic and magnetic properties of the bulk and (001) surfaces of CsXNO (X = Mg, Ca and Sr) quaternary Heusler alloys are investigated. It is found that all of the compounds are half-metallic ferromagnets with a magnetic moment of 2μB which obeys the Slater-Pauling rule. The half-metallic gaps are calculated to be 0.84, 0.80 and...

We have investigated the electronic and optical properties of a penta-BP5 monolayer, using the band structure results obtained through the full potential linearized augmented plane wave method within the density functional theory. The results show that penta-BP5 monolayer has a quasi-indirect band gap of 1.84 eV. The dielectric tensor and correspon...

In this study, the structural, electronic and magnetic properties of silicon carbide monolayer coated with manganese have been investigated. The most stable structure was identified by considering manganese atoms on carbon atoms, silicon atoms, and hexagon centers with doing the complete relaxations of atomic positions cell parameters. The results...
