ALPHA (?):?It is a large signal current gain in common base configuration. It is the ratio of collector current (output current) to the emitter current (input current).It is a current gain in CB amplifier and it indicates that the amount of emitter current reaching to collector. Its value is unity ideally and practically less than unity. Beta (?): It is a current gain factor in the common emitter configuration. It is the ration of collector current (output current) to base current (output current).
a bond is broken on the N- side and the electron freed from the bond jumps to

increase its electrical conductivity
Suitable impurities are added to a semiconductor depending upon its use. This is done to increase its electrical conductivity
6 ev
In case of diamond , the forbidden gap is about 6 ev
raises the potential barrier
When we apply reverse bias to a junction diode it raises the potential barrier
