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 ... -
Raman scattering in layered CdInGaS4
(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 ... -
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 ... -
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 ... -

(Taylor & Francis Ltd, 2017)Studies of temperature behavior of the mean refractive index, ordinary and extraordinary refractive indices, and birefringence have been carried out for three nematogens. The thermo-morphologic properties of the biphasic ... -
Regimes of current transport mechanisms in CdS/CdTe solar cells
(Iop Publishing Ltd, 2019)Forward bias recombination (current transport) mechanisms have been evaluated for thin film solar cells and correlated to the in-gap trap levels present. Here CdTe/CdS devices were chosen as an archetypal example of a ... -
Reversible and irreversible effects after oxygen exposure in thick (> 1 mu m) silicon films deposited by VHF-PECVD on glass substrates investigated by dual beam photoconductivity

Room temperature I-V and C-V characteristics of Au/mTPP/p-Si organic MIS devices
(Edp Sciences S A, 2018)The room temperature electrical characteristics of the organic Au/mTPP/p-Si device fabricated by spin coating method were investigated with I V and C V measurements. It has been determined that the device has a high ... -
Screening theory based modeling of the quantum Hall based quasi-particle interferometers, defined at quantum dots
(Elsevier Science Bv, 2012)In this work, we investigate the spatial distributions and the widths of the incompressible strips, i.e. the edge-states. The incompressible strips that correspond to nu = 1,2 and 1/3 filling factors are examined in the ... -
