Edge defined film fed growth
Edge-defined film-fed growth or EFG was developed for sapphire growth in the late 1960s by Harold LaBelle and A. Mlavsky at Tyco Industries. A shaper (also referred to as a die) having dimensions approximately equal to the crystal to be grown rests above the surface of the melt which is contained in a crucible. Capillary action feeds liquid material to a slit at the center of the shaper. When a seed crystal is touched to the liquid film and raised upwards, a single crystal form… WebThe edge-defined film-fed growth (EFG) method is another highly efficient bulk crystal growth method, and has been widely used in the crystal growth of Si, sapphire, Nd:YVO 4, Ga 2 O 3, etc. 19–27 The EFG method, evolved from the CZ method, employs a die or a shaper placed in the crucible. Compared with that from the traditional Cz method ...
