An ideal germanium pn junction diode has the following parameters: Na = 4 × 10¹5 cm³,
Na = 2 × 10¹7 cm³, D₂ = 48 cm²/s, D₁ = 90 cm²/s, Tpo = T = 2 × 10-6 s, and
A = 104 cm². Determine the diode current for (a) a forward-bias voltage of 0.25 V
and (b) a reverse-biased voltage of 0.25 V.

- Write a complete Java program named FindSumAndAverage that performs the following tasks in 2-D array: Main Method: a. The main() method asks the user to provide the dimension n for a square matrix. A square matrix has an equal number of rows and columns. b. The main() method receives the value of n and calls the matrixSetUp() method that creates a square matrix of size n and populates it randomly with integers between 1 and 9. c. The main method then calls another method named printMatrix() to display the matrix in a matrix format. d. The main method also calls a method named findSumAndAverage() which: • Receives the generated matrix as input. • Calculates the sum of all elements in the matrix. • Calculates the average value of the elements in the matrix. • Stores these values (sum and average) in a single-dimensional array and returns this array • e.
