Lanthanum aluminate(LaAlO3) single crystal as a substrate for high Tc superconducting film has attracted attention recently. We report here a transmission electron microscopy(TEM) study of the crystal structure and phase transformation of LaAlO3 by using Philips EM420 and EM430 microscopes. Single crystals of LaAlO3 were investigated first by optical microscope. Stripe-shaped domains of mm size are clearly seen(Fig.1a), and 90° domain boundary is also obvious. TEM specimens were prepared by mechanical grinding and polishing followed by ion-milling.Fig.lb shows μm size stripe domains of LaAlO3. Convergent beam electron diffraction patterns (CBED) from single domain were taken.Fig. 2a and Fig. 2c are [001] zone axis patterns which show a 4mm symmetry, and the (200) dark field of this zone axis gives 2mm symmetry(fig.2b). Therefore the point group of this crystal is either 4/mmm or m3m. The projection of the first order Laue zone(FOLZ) reflections on zero layer (fig. 2c) shows that the unit cell is face centered. A tetragonal unit ceil is chosen, with a=0.532nm and c=0.753nm, c being determined from the FOLZ ring diameter.

The One

This chapter provides a close reading of Schelling’s early commentary on Plato’s Timaeus and then contrasts this reading with Neoplatonism’s, particularly Proclus’, understanding of this same text. While Neoplatonism views being according to a hierarchy of degradation or descent, with matter at the bottom, Schelling affirms that being potentiates itself into higher and greater degrees of order such that matter is not the last but the first. He is able to do this, however, only by rejecting the Platonic notion of participation. For Schelling, the participating acquires an independence from the participated so that an effect can be greater than its cause and, moreover, the effect exerts a retroactive after effect on the cause. The identity of a cause or antecedent is only constituted in and through its consequents. If matter is said to process from the One, then matter, in turn, is the consequent condition of the identity of the One as one rather than as many.
