Thermal management in electronic devices remains a challenge to this day. Materials exhibiting high thermal conductivity and still being electrical insulators are desired. Single crystals of low-dimensional quantum cuprate oxides have shown high magnetic thermal conductivity at room temperature predominately in one dimension . Thin films of these materials are needed for various applications. To this end, we have been investigating the growth of La5Ca9Cu24O41 thin films on various substrates. In this work we will present results related to the fabrication, morphological and structural characterization of these films.
Epitaxial-like films of La5Ca9Cu24O41 were fabricated on MgO and SrTiO3 single crystal substrates using pulsed laser deposition (PLD) at 248 nm. The target of the exotic complex oxide was ablated at a fluence of 2J/cm2 and 10 Hz. The depositions took place at various substrate temperatures up to 800ºC and in oxygen atmosphere. The effect of substrate temperature on the quality of the thin films will be discussed.
