SUMMARY
The drift velocity of electrons in pure silicon under an electric field of 10^4 V/m can be calculated using the formula v_d = μ * E, where μ is the mobility of electrons in silicon. The mobility of electrons in silicon is approximately 1350 cm²/V·s. Therefore, the drift velocity is approximately 1.35 m/s. To calculate the time taken for an electron to drift 1 µm, use the formula time = distance / velocity, resulting in a time of approximately 0.74 microseconds.
