6.4 (a) A sample of semiconductor has a cross-sectional area of 1 cm² and a thickness
of 0.1 cm. Determine the number of electron-hole pairs that are generated per unit
volume per unit time by the uniform absorption of 1 watt of light at a wavelength of
6300 Å. Assume each photon creates one electron-hole pair. (b) If the excess minority
carrier lifetime is 10 μs, what is the steady-state excess carrier concentration?
6.1 Consider silicon at 7 = 300 K that is doped with donor impurity atoms to a concentra-
tion of Na = 5 x 105 cm³. The excess carrier lifetime is 2 x 10-'s. (a) Determine
the thermal equilibrium recombination rate of holes. (b) Excess carriers are generated
such that Sn = p = 104 cm³. What is the recombination rate of holes for this
condition?
6.18 A semiconductor is uniformly doped with 107 cm³ acceptor atoms and has the fol-
lowing properties: D = 27 cm²/s, D = 12 cm²/s, T = 5 × 10-7 s, and 7po = 10-7 s.
An external source has been turned on for 1 <0 producing a uniform concentration of
excess carriers at a generation rate of g = 10 cm³ s. The source turns off at time
1 = 0 and back on at time = 2 × 10-6 s. (a) Derive the expressions for the excess
carrier concentration as a function of time for 01, (b) Determine the value of
excess carrier concentration at (i) 1 = 0, (ii) 1 = 2 × 10-6 s, and (iii) t = x. (c) Plot
the excess carrier concentration as a function of time.
