Thermal conductivity of Ni, Co, and Fe-doped La5Ca 9Cu24O41 thin films measured by the 3ω method
(2010)
The effect of Ni-, Co- and Fe-substitution for Cu on the thermal conductivity of La5Ca9Cu24O41 thin films is investigated. Highly b-axis oriented polycrystalline films were grown onto MgO (100) substrates using the pulsed ...
Growth and structural characterization of orthorhombic and tetragonal SrCuO2 thin films
(2013)
Epitaxial SrCuO2 thin films were grown on (0 0 1) SrTiO 3 substrates by pulsed laser deposition using a stoichiometric target. X-ray diffraction indicated that the SrCuO2 films undergo a structural phase transition as a ...
Pulsed laser deposition and thermal characterization of Ni-doped La5Ca9Cu24O41 thin films
(2011)
Highly b-axis oriented polycrystalline Ni-doped La5Ca 9Cu24O41 thin films have been grown on (0 0 1) SrTiO3 substrates using the pulsed laser deposition technique. EDX measurements have revealed nearly stoichiometric ...
Memristive and neuromorphic behavior in a Li x CoO 2 nanobattery
(2015)
The phenomenon of resistive switching (RS), which was initially linked to non-volatile resistive memory applications, has recently also been associated with the concept of memristors, whose adjustable multilevel resistance ...
Resistive switching phenomena in Li xCoO 2 thin films
(2011)
A substantial resistive switching of Li xCoO 2 mixed-conductor thin films is observed for the first time. The occurrence of possible bipolar switching in these oxide thin films is by current-voltage curves, investigated ...
Growth and transport properties of HT-Li xCoO 2 thin films deposited by pulsed laser deposition
(2012)
The successful in situ growth of single phase, c-axis oriented, layered structured Li xCoO 2 thin films on (0 0 0 1) Al 2O 3 substrates by pulsed laser deposition is reported. Thin films were grown in an oxygen pressure ...
Optical probing of anisotropic heat transport in the quantum spin ladder Ca 9La 5Cu 24O 41
(2012)
A transient thermal imaging technique is used to monitor heat diffusion at the surface of the antiferromagnetic spin ladder material Ca 9La 5Cu 24O 41. This material shows highly anisotropic thermal conductivity due to a ...
KrF pulsed laser deposition of La5Ca9Cu24O41 thin films on various substrates
(2009)
Recent studies on single crystals of cuprate oxides containing spin chains and ladders have reported large anisotropic magnon-mediated thermal conductivity. A potential use of thin films of such materials could be in the ...
Pulsed laser deposition of homo- and hetero-epitaxial thin films of the exotic La5Ca9Cu24O41 compound on oxide and Si substrates
(2010)
Pristine and transition metal-doped La5Ca9Cu 24O41 thin films were fabricated by pulsed laser deposition in oxygen atmosphere. The effect of magnetic doping, type of substrate and growth temperature on the crystallographic ...
