Superconducting multilayers, whose growth and structure are determined by the kinetic deposition instead by thermodynamics, are a powerful tool for investigating high T c superconductors (HTSC) properties. By means of Pulsed Laser Deposition (PLD), we grew such materials alternating infinite layer phases both pure and doped, to supply Cu0 2 planes and charge reservoir (CR) blocks respectively. We found out that using chemically doped CR leads to a semiconducting behavior, whereas oxygen doping seems to be much more effective, since the BaCu0 2 infinite phase, grown in high oxygen partial pressure, does actually bring about a superconducting behavior. We deposited BaCu0 2 /CaCu0 2 superlattices with various periodicities and studied their transport and structural properties. By varying the deposition parameters, we reached both kinetic and thermodynamic growth and we observed semiconducting and superconducting behaviors.

“…With a strain effect from an appropriate substrate, film deposition methods are a possible way to fabricate this kind of metastable material. Actually, there were a few reports about the (Cu,C)-1234 films fabricated by pulsed laser deposition (PLD) method [10][11][12][13][14], sputtering method [15] and molecular beam epitaxy (MBE) method [16,17]. However, all these previous films exhibited relatively low zero-resistance critical temperature (T c0 ) or even no superconductivity, and the maximum T c0 was only 78 K reported previously [12] and has never been improved any more.…”

Cu,C)Ba 2 Ca 3 Cu 4 O 11+y is a nontoxic cuprate system with a superconducting transition temperature (T c ) of about 117 K for bulk samples. Recently, it is found that the bulk samples of this material synthesized under high pressure hold the highest irreversibility line among all the superconductors, which is very promising for the application in the liquid nitrogen temperature region. In this paper, we report successful growth of a-axis oriented (Cu,C)Ba 2 Ca 3 Cu 4 O 11+y films by pulsed laser deposition method on LaAlO 3 (001) substrates. The maximum zeroresistance T c obtained in our work is as high as 96 K which is 18 K higher than the T c reported previously in this system. The magnetization and resistivity measurements reveal that the superconducting properties of the films are significantly improved. These newly observed properties enhance the prospect of potential applications of this material.

“…Within the class of oxycarbonate materials, pulsed laser deposition (PLD) has been used for the synthesis of BaCa-Cu, Sr-Cu, and Ba-Sr-Cu oxycarbonate thin films, which have been studied as superconductors [7][8][9][10].

“…In all of these reports [7][8][9][10], pure oxide materials were used as pulsed laser deposition targets. Oxycarbonate thin films were obtained by postdeposition furnace annealing [8] or by in situ annealing of deposited films at higher gas pressure [7,9,10]. In general, rare earth oxycarbonates are stable compounds in ambient conditions.…”

Rare earth oxycarbonates are potential candidate materials for constructing simple and low-cost chemiresistive sensors for monitoring carbon dioxide (CO 2 ) gas in the living and working environment for personal comfort and health reasons. Also, measurement of CO 2 concentrations is needed in many industrial processes. Specifically, sol-gel made nanoparticles of Nd and La oxycarbonates have been studied previously as novel CO 2 gas sensor materials. In this paper, pulsed laser deposition of La oxycarbonate (La 2 O 2 CO 3 ) thin films was studied and structural properties of obtained thin films were characterized. Also, CO 2 gas sensing ability of synthesized films was evaluated. The films deposited under CO 2 partial pressure in various conditions were all Raman amorphous. In situ or ex situ annealing procedure at high CO 2 partial pressure was needed for obtaining crystalline La 2 O 2 CO 3 films, whereby hexagonal and monoclinic polymorphs were obtained in ex situ and in situ processes, respectively. Sensor structure, made using in situ process, was sensitive to CO 2 gas and showed relatively fast response and recovery characteristics.
