DIODE,is the combination of pn junction. in the sence doping the impurites in the required quantities.i think there are two types of impurites ie.,silicon and germanium.

main function of a diode is working in forward bias & reverse bias. in the sence flow of current.
APPLICATIONS:
1.rectefiers
2.used as GATES(AND,OR...)
3.protection circuit for polarity preferences

WORKING CONDITIONS:
1. for silicon biasing current is 0.7v.but practicaly it's 0.6
2. for germanium biasing current is 0.3v.
