A substrate for epitaxial growth, which is capable of improving a surface state of an epitaxial layer at microroughness level. Polymers with low dispersities and molecular weights from 1000 to 3000 are synthesized in reversed micelles and biphasic systems. The method may comprise applying a first voltage potential to a first N-doped region via a bit line and applying a second voltage potential to a second N-doped region via a source line. Furthermore, a plurality of second candidacy pose information is generated according to the first pose information respectively. In one embodiment of the inventions application, the housing is secured to a percussion rock drill and the rail secured in a position to allow drilling as desired. The system comprises a plasticator and press.
