Surface optical phonons are normally considered as subtle and poorly reproducible features in the Raman spectra of nanostructured semiconductors, from which little or no information about the sample can be extracted. The present study demonstrates th

Strong resonant enhancement of Raman scattering on photonic resonance was observed in GaAsP semiconductor nanowires. The enhancement allowed for detailed studies of the surface phonon polariton (SPhP) scattering peak on individual nanowires. In parti

© 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim The recently proposed highly efficient route of pyridine-catalyzed CO 2 reduction to methanol was explored on platinum electrodes at high CO 2 pressure. At 55 bar (5.5 MPa) of CO 2 , the bulk electro

There are a number of situations where individuals wish to communicate verbally but are unable to use conventional means-so called 'silent speech'. These include speakers in noisy and covert situations as well as patients who have lost their voice as

A new approach to the possibilities of increase in the light yield (LY) of scintillations in lead tungstate (PWO) is discussed. The abrupt LY decrease above 200 K is connected with the start of rotations of WO 4 tetrahedra which disturbs electrostati

High pressure provides an efficient way of controlling the electronic properties of semiconductor nanostructures. We use pressure to tune electronic coupling in stacks of self-assembled quantum dots (SAQDs). The coupling occurs as soon as the distanc

Emission lines from individual InAs self-assembled quantum dots (SAQD) have been observed in electroluminescence spectra from small-area p–i–n light-emitting-diode heterostructure devices containing an embedded layer of SAQD. In the energy range

Structural parameters of InGaAs/GaAs self-assembled quantum dots (SAQDs), which were grown using In-flush technique, were deduced using optical spectroscopy combined with computer modeling. The results are in excellent agreement with the experimental
