Specific heat of strontium titanate (SrTiO3) in the range 0

Specific heat of strontium titanate (SrTiO3) in the range 0.5 to 6 K. Henning, I.; Hegenbarth, E. (Sect. Phys., Tech. Univ. Dresden, Dresden DDR-8027, Ger. Dem. Rep.). Phys. Status Solidi A, 83(1), K23-K26 (English) 1984. CODEN: PSSABA. ISSN: 0031-8965. DOCUMENT TYPE: Journal CA Section: 69 (Thermodynamics, Thermochemistry, and Thermal Properties) The heat capacities of SrTiO3 [12060-59-2], single crystals and ceramic, were measured by the heat-pulse method in a 3He cryostat. This was the 1st attempt to measure at <1.5 K. A Schottky anomaly exists in the single crystals and the polycrystals show glass-like behavior. A possible explanation of the Schottky contribution in SrTiO3 single crystal is a steric rotation of the TiO6 groups in paraelec. domain walls. Such conclusion agrees with the observation of the thermal cond. behavior, earlier noted by E. Fischer (1983).

Conversion of ionizing radiation energy in a cell with a semiconductor electrode: Charge separation in the semiconductor and the quantum yield. Krotova, M. D.; Morozov, A. M.; Sakharova, A. Ya.; Pleskov, Yu. V. (Inst. Elektrokhim., Moscow, USSR). Elektrokhimiya, 21(1), 99-102 (Russian) 1985. CODEN: ELKKAX. ISSN: 0424-8570. DOCUMENT TYPE: Journal CA Section: 72 (Electrochemistry) Section cross-reference(s): 71 In a cell with a single-crystal SrTiO3 [12060-59-2] electrode during irradn. by pulsed accelerated e (4 MeV), the quantum yield of radiation-electrochem. current is 1-10. The efficiency of radiation energy conversion to chem. energy in the decompn. of H2O amts. to 10-4 %. On porous ceramic TiO2 [13463-67-7] electrodes, the efficiency of radiation-electrochem. decompn. of H2O was 2 orders of magnitude higher than on smooth electrodes.
