  1. Question 1

    Q1. The Hall coefficient of a semiconductor is 10^(-4) m³/C. What is the carrier concentration?

    • A) 10²2 m^(-3)
    • B) 6.25 * 10²2 m^(-3)
    • C) 10²0 m^(-3)
    • D) 10^18 m^(-3)

    Answer: 6.25 * 10²2 m^(-3)

    Explanation: Using R_H = 1 / (nq), we can find n = 1 / (R_H * q) = 6.25 * 10²2 m^(-3) for q = 1.6 * 10^(-19) C.
