A semiconductor has an intrinsic charge carrier density of 1×10¹⁴cm3 ,a charge carrier lifetime of 10us, an electron diffusion coefficient of 36 cm²/s, and a hole diffusion coefficient of 12cm²/s. It is at a temperature of 450K and is illuminated by a laser beam at an optical generation rate of 10¹⁹ electron‐hole‐pairs/(cm³∙s) What is the separation between the electron and hole quasi‐Fermi levels? Show these quasi‐Fermi levels on a rough sketch of the energy band diagram with the intrinsic, conduction band, and valence band energy levels. What is the change in the semiconductor's conductivity due to the illumination?

Question regarding piezoresistive accelerometers: How do they achieve low cross-axis sensitivity piezoresistive accelerometer?

a) Design and implement a combinational circuit that converts excess-3 to BCD code using 2-input NAND gates. (Design: means show all the steps)

b) Draw the logic diagram of 2x4 decoder using NOR gates only. Include an enable input. (describe in details)

c) Construct a 5-to-32-line decoder with four 3-to-8 decoders with enable and a 2-to-4-line decoder. Use block diagrams for the components. (Describe in details while you are constructing the required circuit)

d) Design a 2-bit multiplier using a set of Multiplexers and 2-input NAND gates (Design: means show all the steps)

Design a synchronous 3-bit binary counter that generates the repeated sequence of 0, 3, 4, 7, 0, 3, 4, 7, 0… The outputs of the flip-flops are to be the binary output signals of your counter. Your solution needs to include the input equations for the flip-flops, and a circuit diagram for each version. a) Design the counter using D flip-flops b) Design the counter using T flip-flops c) Design the counter using JK flip-flops

Explain why the width of a pn junction can be manipulated by an external volatge. Determine the polarity of the external voltage if one wants to increase the width of the pn-junction.

Design and program an Arduino-based circuit that contains the following items
- 1 Arduino Uno microcontroller.
- 1 IR remote control,
- 1 IR sensor
- 1 LCD 16x2 Display
- Any other components you find necessary.
The circuit will do the following:
- The circuit represents a 2-digit calculator.
- At start of operation, the LCD display should display “0” in line 2 of the LCD display.
- Pressing the On/Off button on the IR remote represents the “Clear” button of the calculator, the VOL+ represents the “+” button, the VOL- represents the “-” button, the |<< represents the “X” button, the >>| represents the “/” button, the EQ represents the “=” button, and the digits represent the digits on the calculator.
- The system expects always the following sequence of keys:
[1] Clear,
[2] a digit (representing the 10s of first number),
[3] a digit (representing the ones of first number),
[4] an operation (+, -, X, /),
[5] a digit (representing the 10s of the second number),
[6] a digit (representing the ones of the second number),
[7] Equal
- After a correct sequence of presses is input (total of 7 presses), the display should display something like the following on the two lines of the LCD:
“17+29= ”
“46 ”
- If a wrong sequence of buttons is pressed, for example: “Clear, 9, X, +, …. “, the system should display “ERROR” in the upper line of the LCD.
- You may need to use the “#include <string.h>”
