PULSED-LASER DEPOSITION OF SRCUO2 CACUO2 SUPERLATTICES/

We have shown that the pulsed laser deposition (PLD) technique, with n o in situ diagnostic, can be used to grow good quality superlattices b ased on the infinite layer compounds SrCuO2 and CaCuO2. We demonstrate d that the major source of disorder in these superlattices, grown at t emperatures lower than 600 degrees C, comes from random discrete thick ness fluctuations. However the random discrete thickness fluctuations affect essentially only one unit cell. This makes the PLD technique ve ry attractive for the growth of new artificial high-T-c structures bas ed on the infinite layers compounds. (C) 1996 American Institute of Ph ysics.
