1. Depletion layer has (for an unbiased PN junction): (1999)
2. Assertion (A): The probability of electrons to be found in the conduction band of an intrinsic semiconductor at a finite temperature decreases exponentially with increasing band gap. Reason (R): It is more difficult for the electrons to jump to the conduction band from the valence band if the band gap between them is large.  
3. Assertion (A): In an oscillator, the feedback is in the same phase which is called as positive feedback. Reason (R): If the feedback voltage is in opposite phase the gain is greater than one.
