QUESTION: 1
Silicon at T=300K contains a acceptor impurity concentration at
Na=1016 cm-3. Determine the concentration of donor impurity atoms
that must be added so that the silicon is n-type and the Fermi energy is
0.20eV below the conduction band edge. [Take NC=2.8 x 1019cm-3].
QUESTION:2
Two semiconductor materials have exactly the same properties except
that material A has a band gap energy of 1.0eV and material B has a
band gap energy of 1.2eV. Determine the ratio of n of material A to
that of material B for T=30OK.
QUESTION:3
A special semiconductor material is to be "designed". The
semiconductor is to be n-type and doped with 1 x 1015 cm3 donor
atoms. Assume complete ionization and that Na=0. The effective
density of state functions are given by Nc = Nv =1.5 x 1019 cm-3 and are
independent of temperature. A particular semiconductor device
fabricated with this material requires the electron concentration to be
no greater than 1.01 x 1015 cm³ at…
