چکیده

The new phase Ba5In2Al2Zr0.9Nb0.1O13.05 with hexagonal perovskite structure was obtained. substitution of Zr4+ by smaller Nb5+ accompanied the incorporation oxygen interstitials and did not lead to a significant change in lattice parameters. It established that investigated sample capable for water from gas phase, hydration degree value 0.24 mol H2O. IR-spectroscopy analysis defined presence OH−-groups different thermal stability, which participate hydrogen bonds. demonstrates predominant protonic conductivity at pH2O = 2·10−2 atm Т600 °C.

Electrical transport properties of Si-doped hexagonal boron nitride epilayers

The suitability of Si as an n-type dopant in hexagonal boron nitride (hBN) wide bandgap semiconductor has been investigated. Si doped hBN epilayers were grown via in-situ Si doping by metal organic chemical vapor deposition technique. Hall effect measurements revealed that Si doped hBN epilayers exhibit n-type conduction at high temperatures (T > 800 K) with an in-plane resistivity of ∼12 · cm,...

A novel perovskite-like Ta-bronze KTa1+zO3: preparation, stoichiometry, conductivity and crystal structure studies.

A new cubic Ta-bronze (1) KTa(1+z)(+(5-delta))O(3) [z approximately 0.107 (3)] was obtained on a cathode by molten salt electrolysis of the system K(2)TaOF(5)-K(3)TaO(2)F(4)-(KF + NaF + LiF)(eutectic). Black, metallic cubic crystals of (1) are formed together with tetragonal beta-Ta. The perovskite-like crystal structure of (1) [a = 4.005 (1) A, space group Pm3m] was refined with anharmonic dis...

Conductivity and switching phenomena in Mn-doped perovskite single crystals and manganite thin films

For better understanding of the charge-transport mechanisms in perovskite manganites, along with colossal magnetoresistance ~CMR! materials, such as La12xSrxMnO3, we study systems with decreased content of Mn ions, such as single crystals of LaGa12xMnxO3 (0,x,0.5). The conductivity of all the systems in study can be described adequately with a nonadiabatic approximation of the hopping model wit...

Structure–conductivity correlation in ferric chloride- doped poly(3-hexylthiophene)

Poly(3-hexylthiophene) (P3HT) matrix has been chemically doped (redox doping) by ferric chloride (FeCl3) with different molar concentrations to get P3HT–FeCl3 charge-transfer complexes. The effect of redox doping on photo-physical, structural, and morphological properties and dc electrical conductivity of P3HT matrices has been examined. The dc conductivity has been measured on films of pristin...
