Describe the alloyed junction method of forming a semiconductor.
What will be an ideal response?
The alloyed junction method of forming a semiconductor is extremely simple. A small pellet of trivalent material, such as indium, is placed on an N-type semiconductor crystal. The pellet and crystal are heated until the pellet melts and partially fuses with the semiconductor crystal. The area where the two materials combine forms the P-type material. When the heat is removed, the material recrystallizes and a solid PN junction is formed.
