6 * this program tries helping to understand the amorphous depuration
7 * and recrystallization of SiCx while ion implantation at temperatures
8 * below 400 degree celsius.
9 * hopefully the program will simulate the stabilization of the
10 * selforganizing lamella structure in the observed behaviour.
