  • METHOD
    Publication number: 20220259730
    Abstract: The invention relates to methods for the formation of rare earth nickelate thin films and “doped” (i.e. cation-substituted) variants thereof on a substrate using atomic layer deposition (ALD). The films can be deposited at low temperature (e.g. at temperatures as low as 225° C.) and have a range of useful properties including good crystallinity and high electrical conductivity, as well as interesting magnetic, optic and catalytic properties. These properties make the materials suitable for use in microelectronic applications, in the production of electrodes and as catalytic surfaces.

  • Formation of a lithium comprising structure on a substrate by ALD
    Patent number: 8894723
    Abstract: A method for the formation of lithium includes a layer on a substrate using an atomic layer deposition method. The method includes the sequential pulsing of a lithium precursor through a reaction chamber for deposition upon a substrate. Using further oxidizing pulses and or other metal containing precursor pulses, an electrolyte suitable for use in thin film batteries may be manufactured.
