Step 1
Phosphorus is a pentavalent impurity, meaning it has five valence electrons. When it is added to silicon, it donates one electron to the conduction band, becoming a donor impurity. Show more…

Find the thermal-equilibrium electron and hole concentrations in silicon with doping concentrations of Na = 7 X 1015 cm-3 and Na = 3 X 1015 cm-3 for (a) T = 250 K and (b) T = 400 K.

Find the electron and hole concentrations and Fermi level in silicon at 300 K (a) for 1 x 10^15 boron atoms/cm^3 and (b) for 3 x 10^16 boron atoms/cm^3 and 2/9 x 10^16 arsenic atoms/cm^3. The first two are acceptor concentrations, and the third one is an donor concentration.

A) For a P-type silicon in which the dopant concentration Na = 5 x 10^18/cm^3, find the hole and electron concentrations at T=300K. B) Contrast the electron and hole drift velocities through a 10 micrometer layer of intrinsic silicon across which a voltage of 3V is imposed. Let un = 1350 cm^2/V*s and up = 480 cm^2/V*s.
