ABSTRACT
We investigate optical responses of arrays of flat, quasitriangular nanoparticles made by the self-assembly sphere lithography of a 20 nm thick gold film. The measured optical absorption spectra show strong, particle size dependent resonances, in excellent agreement with our simulations. We identify those resonances as due to standing surface/edge plasmon-polariton waves.

    Thin films of a delafossite compound CuScO2 were grown on spinel MgAl2O4 (111) substrates, yielding in highly crystalline and (0001)-oriented epitaxial structures. Absorption spectra at 20 K revealed a sharp exciton resonance at 3.97 eV, which persisted up to 300 K. Its direct transition band...

    The excitonic absorption spectra of thin films of ferroelectric Cs2CdI4 and Cs2ZnI4 solid solutions are studied for the first time. It is found that, within the whole range of molar concentrations x, the spectra of Cs2(Cd1 − xZn x)I4 comprise two bands that originate from the bands of the...

    We propose an asymmetric bilayer structure in which the magnetic remanence (MR) is controlled by the in-plane strain of the top NiFe2O4 (NFO) layer epitaxially constrained by the bottom Pb(Mg1/3Nb2/3)O3-PbTiO3 (PMN-PT) substrate. In this asymmetric structure, an electric-field-induced giant...

    The absorption spectrum of thin films of a new compound, K2CdI4, was studied. It was established that this compound belongs to direct-bandgap dielectrics and that its low-frequency electronic and excitonic excitations are localized in CdI2–4 structural blocks of the crystal lattice. It...

    Ternary Zn1-xCdxO films were grown on (0001) sapphire substrates by pulsed laser deposition. The energy band gap of Zn1-xCdxO films decreases with increasing Cd content. An increase of Cd content also leads to the emission broadening, absorption edge broadening, and crystallinity degradation....
