Which of the PN-junction is forward biased?

A PN-junction has a thickness of the order of :

The output of an AND gate is connected to both the inputs of a NOR gate, then this circuit will act as a 

In a p-type semiconductor, the acceptor level lies 

In the following common emitter circuit if $$\beta = 100, V _ { C E } = 7 V , V _ { B E } = \text { negligible, } R _ { C } = 2 \mathrm { k } \Omega $$ then $$I _ { B }$$ is

The equivalent circuit is : 

When PN junction os forward biased , the current in junction 

Energy bands in solids are a consequence of

Find the value of $${ V }_{ 0 }$$

For the circuit show below, the current through the zener diode is :
