1. What happens to the thickness of the depletion region in a PN junction when an external voltage is applied to a forward bias diode? 2. When “P” and “N” type semiconductor pieces are brought into close contact, free electrons from the “N” piece will rush over to fill holes in the “P” piece, creating a zone on both sides of the contact region devoid of charge carriers. What is this zone called, and what are its electrical characteristics 3. Is this diode forward-biased or reverse biased? Show soultion please, thanks.
Q6:- (a) Using diode equation, determine the diode current at 20°C for a silicon diode with n=2, Is=0.1μA at a reverse-bias potential of -10 V. (b) Is the result expected? Why?
Young's experimental setup can be used to monitor the width of the lead wires in transistors. The cables are placed in a narrow opening as shown in the figure. The opening is illuminated with highly coherent light. The position of the tenth maximum is measured on a screen located at 0.5m. The expected diameter of the wires is 0.100±0.005 mm. (a) What is the maximum deviation that the position of the tenth maximum can have so that the cable has an acceptable diameter? What would happen if the first maximum was used as the criterion, would the decision be easier or more difficult?
