Quantum Hall effect in a high-mobility two-dimensional electron gas on the surface of a cylinder
(Amer Physical Soc, 2009)The quantum Hall effect is investigated in a high-mobility two-dimensional electron gas on the surface of a cylinder. This special topology leads to a spatially varying filling factor along the current path. The resulting ... -

(2004)Raman scattering spectra of CdInGaS4 crystals grown by the chemical transport method were measured at room and liquid-nitrogen temperatures. Band pairs at 29-38, 43-48 and 60-65 $cm^{-1}$ are reported for the first time. ... -
Raman scattering under pressure and the phase transition in epsilon-GaSe
(Wiley-V C H Verlag Gmbh, 2003)Raman scattering in epsilon-GaSe has been investigated at room temperature in a diamond anvil cell by using helium gas as a pressure transmitting medium. The first observation of the solid-solid phase transition under ... -
Rapid Reversible Degradation of Silicon Thin Films by a Treatment in Water
(Iop Publishing Ltd, 2012)Metastability effects in amorphous and microcrystalline silicon thin films induced by exposure to atmospheric gases and water are investigated. A simple procedure is described which allows studying such effects in a ... -
A rapid synthesis of 2-substituted 1,2,3-triazole-1-oxide derivative starting from 4-(methyl)isonitrosoacetophenone and its Ni(II) complex: Characterization, DNA binding and cleavage properties
(Elsevier Science Bv, 2017)An efficient route, not including any metal salt as a catalyst, for the synthesis of a new 2-substituted 1,2,3- triazole-1-oxide is reported in this paper. The title compound has been synthesized via reacting 4-(methyl)i ... -
Rarely convergent sequences in topological spaces
(Academic Publication Council, 2020)In this work, by using rare sets, we introduce a new type of convergence in topological spaces, called rare convergence, which is weaker than ordinary convergence. After presenting some examples, we investigate the ... -
Rational (Pade) approximation for estimating the components of the partially-linear regression model
(Taylor & Francis Inc., 2021)This paper proposes a new smoothing technique based on rational function approximation using truncated total least squares (P - TTLS) and compares it with the widely used smoothing spline method, which has become a very ... -
Real gamma scattering at TESLA x N collider
(2001)The proposal for measurement of polarized gluon and quark distributions in scattering of polarized real y beam on polarized nuclear target have been considered. High energy y beam is obtained by backscattering of laser ... -

(Institute of Physics Publishing, 2019)The fabrication of self-standing porous carbon foam nanostructures for trapping sulfur in Lithium-Sulfur (Li-S) batteries was aimed in this work. Nitrogen doped reduced graphene oxide/acid treated MWCNT based cathode ... -
Reflective light modulator based on epsilon-GaSe crystal
(Optical Soc Amer, 2002)We report the results of investigating a low-voltage, polarization-insensitive, reflective-type modulator based on an epsilon -GaSe crystal and operated at the 1.960-eV line of a He-Ne laser. We demonstrate that the ... -
Refractive and birefringent properties and order parameter of nematic liquid crystal at the direct and reverse nematic <-> isotropic liquid phase transition
(Natl Inst Optoelectronics, 2016)Temperature dependences of the refractive indices, birefringence and molecular polarizability in large temperature interval and especially in the region of the direct nematic mesophase - isotropic liquid (for the heating ... -
