Abstract: The embodiments herein provide a Crystalline Strontium Titanate (STO) and a method for deposition of the STO on a silicon substrate. The embodiments herein utilize radio-frequency (RF) magnetron sputtering to grow crystalline pure phase Strontium Titanate SrTiO3 (STO) with single orientation upon a surface of oriented Silicon (Si) substrates followed by annealing at 800° C. for 1 hour in ambient conditions. Furthermore, the embodiments herein completely eliminates the buffer layer which is generally needed beneath the STO thin films, making the deposition of STO films on silicon substrates much more cost-effective than the existing method. Hence a single crystal STO film is directly obtained on the silicon substrate at the end of the process.

Abstract: The embodiments herein provide lithium iron phosphate (LFP) cathode active materials and a method for deposition of the LFP active materials on an aluminum-foil current collector for lithium-ion (Li-ion) batteries. The embodiments herein utilize an aqueous based LFP precursor slurry made using combustion chemistry, where the LFP precursor slurry is composed of a redox mixture of the nitrates of lithium and iron, dihydrogen ammonium phosphate and glycine in water in the presence of flora-based sodium-carboxy methylcellulose as an organic binder. Furthermore, the thick and transparent precursors slurry is deposited on the aluminum current collector followed by annealing at appropriate pressures and atmospheric conditions. Therefore, the heat liberated in the exothermic reaction of the redox mixture not only assists in the formation of LFP cathode active materials, but also in the incineration of the organic binders and the solvent.

Abstract: A method and a system for fabricating superconducting nanowire single photon detector (SNSPD) is disclosed. The superconducting nanowire single photon detector consists of a thin film of superconducting material shaped into a meandering nanowire through nanofabrication processes. The pattern enables the nanowire to cover a wide surface area. The SNSPD is a type of near-infrared single-photon detector based on a current-biased superconducting nanowire. The method includes depositing a plurality of buffer layers on a substrate of a superconducting nanowire single photon detector using a pulsed laser deposition technique. The method further includes designing deposited buffer layer into a desired pattern of nanostrips and depositing a plurality of high temperature superconductor (HTS) on the desired pattern of nanostrips. To obtain the desired pattern, at least one of lithography and/or etching processes is used in the SNSPD.
