Step PN Junction - Energy Band Diagram

AI Thread Summary
A step pn junction diode in silicon is characterized by an n side doping concentration of N'D = 2x10^16 cm^-3 and a p side doping of N'A = 5x10^15 cm^-3. The discussion focuses on drawing the energy band diagram of the junction at equilibrium and calculating the built-in voltage. Participants express difficulty in starting the problem, indicating a need for guidance on the initial steps. The built-in voltage should be compared with the value obtained from the drawn diagram. Understanding these concepts is crucial for solving the remaining parts of the question.

A step pn junction diode is made in silicon with the n side having N'D = 2x10^16 cm^-3 and the p side having a net doping of N'A = 5x10^15 cm^-3.

1). Draw to scale the energy band diagram of the junction at equilibrium.
2). Find the built-in voltage, and compare with the value measured off your drawing in 1).

There are 9 parts to this question, but I cannot seem to find out how to start it off. I've tried for 3 hours and couldn't make any progress. The other parts are somewhat related.

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
