Blue phase colloidal crystals and dielectric nanoparticle/polymer doped blue phases are demonstrated to combine multiple components with different symmetries in one photonic material, creating a photonic crystal with variable and micro-controllable photonic band structure. In this composite photonic material, one contribution to the band structure is determined by the 3D periodic birefringent o...

Abstract The electronic inhomogeneities in Co, Ni, and Cr doped BaFe 2 As single crystals are compared within three bulk property regions: a pure superconducting (SC) dome region, coexisting SC antiferromagnetic (AFM) non-SC region. Machine learning is utilized to categorize the inhomogeneous states: in-gap, L-shape, S-shape states. Although relative percentages of states vary samples, total vo...

A series of yttrium-doped CdO (CYO) thin films have been grown on both amorphous glass and single-crystal MgO(100) substrates at 410 degrees C by metal-organic chemical vapor deposition (MOCVD), and their phase structure, microstructure, electrical, and optical properties have been investigated. XRD data reveal that all as-deposited CYO thin films are phase-pure and polycrystalline, with featur...

In this study, the electrodeposition (ED) of ultrathin, compact TiO2 blocking layers (BLs) on fluorine-doped tin oxide (FTO) glass for perovskite solar cells (PSCs) is evaluated. This bottom-up method allows for controlling the morphology and thickness of TiO2 films by simply manipulating deposition conditions. Compared with BLs produced using the spin-coating (SC) method, BLs produced using ED...

We report superconducting (SC) properties of stoichiometric LiFeAs (T(c)=17 K) studied by small-angle neutron scattering (SANS) and angle-resolved photoemission (ARPES). Although the vortex lattice exhibits no long-range order, well-defined SANS rocking curves indicate better ordering than in chemically doped 122 compounds. The London penetration depth lambda(ab)(0)=210+/-20 nm, determined from...

We investigate the issues of competing orders and quantum criticality in cuprate super-conductors via experimental studies of the high-field thermodynamic phase diagrams and the quasiparticle tunneling spectroscopy. Our results suggest substantial field-induced quantum fluctuations in all cuprates investigated, and their correlation with quasiparticle spectra implies that both electron-(n-type)...

Wurtzite-type aluminum scandium nitride [WZ-(Al1−xScx)N] thin films were grown on 0.5 wt % Nb-doped SrTiO3(111) (Nb:STO) single crystal substrates using the radio frequency reactive magnetron sputtering method with Al and Sc targets. WZ-(Al1−xScx)N 0 ≤ x 0.49 epitaxially Nb:STO substrates. Films 0.3 exhibited multi-domain in-plane orientation. The coexistence of two rotation domains, (Al,Sc)N[1...

In this paper we report the successful synthesis of the cubic oxyanion containing perovskites, Ba(2)Sc(2-x)P(x)O(5+x) (x = 0.4, 0.5), with the samples analysed through a combination of X-ray diffraction, NMR, TGA, Raman spectroscopy and conductivity measurements. Conductivity measurements indicate a p-type contribution to the conductivity in oxidizing conditions at elevated temperatures, with e...
