Leo the Great (440-61), who first appropriated the old pagan title of pontifex maximus, intervened with his Tome at the Council of Chalcedon to establish orthodox Christology, told a recalcitrant archbishop that he merely "participated in" a "fullness of power" reserved to popes alone (this later to become an important principle in canon law), and provided in his letters and sermons a highly influential description of the Petrine office and its primacy, drawing in part upon principles found in Roman law.

His letter to Sergius with great politeness explains that he had said the emperor was wrong, and had quoted the famous words of St. Leo's Tome to Flavian:"Agit utraque natura cum alterius communione quod proprium est" as plainly defining two distinct but inseparable operations; Sergius was responsible for leading him into error by sending him the letter of Mennas.

It is well known that the large lattice mismatch (16%) and thermal expansion coefficient mismatch between GaN and sapphire substrate are the main origins of TDs. By new growing technique of LEO, we acquired high quality GaN films almost free of TDs. The stress characteristics in GaN films with MLTB growing technique is dependent on growing systems and conditions, and the changes of stress and dislocation density are rightabout; Combining buffer layers of high temperature and low temperature is first developed to growing GaN films with low dislocation density, and the mechanism of lowering TDs density is that the first buffer layer of high temperature can make nuclear in second buffer layer of low temperature bigger. This technique also can restrain yellow luminescence effectively.
