We have grown La2-xSrxCuO4 (x = 0.1-0.15) single crystalline films on different single crystalline substrates e.g., La2Cu1-yZnyO4 (y = 0.05), La2-xSrxCu1-yZnyO4 (x = 0.15, y = 0.05), La2-xBaxCuO4 (x = 0.113), La2-xSrxCuO4 (x = 0.186), LaSrAlO4, La2-xSrxCu1-yAlyO4 (x = 0.25, y = 0.03) etc., using infrared-heated liquid phase epitaxy technique (IR-LPE). The superconducting properties of the film were found to vary significantly depending on the lattice mismatch with different substrates. Closer lattice matching between film and substrate enhanced the Sr-concentration in film grown under identical conditions. IR-LPE technique was found to be a more effective technique to apply higher epitaxial strain on La2-xSrxCuO4 films than other epitaxy techniques using smaller lattice mismatch.
