The ionic crystal of NaCl has an fcc structure as
shown below with the position of the Cl atom
located at : (0 0 0); (½ ½ 0); ( ½ 0 %) and (0
½) and Na atom is located at : (½ ½½) + fcc
translation.
The following are the physical data of NaCl:
- Ionic radius Na = 0.98 A, Cl ion radius
1.81 A
Atomic mass of Na = 22.99 amu, Atomic
mass of Cl = 35.45 amu
NaCl bulk modulus = 2.40 x 1010 N/m
- Madelung's constant = 1.75
Young's modulus in the direction [100] = 5
x 1010 Nm-2
Debye temperature = 281 K
-
State the structural factors of NaCl, F in
fNa and fCl (f = atomic scattering factor).
Also determine the condition (h k 1) so that
the value of F = 0.
Cu
Assume that the crystal structure of metallic copper (Cu) results in a density of atoms p = 8.46 × 10²m
3. Each Cu atom in the crystal donates one electron to the conduction band, which leads, for the 3-D Fermi
gas, to a densityu of states
g(ɛ) =
2 x = ( 2 m ² ) ²
1/2
where m is the effective mass of the conduction electrons. In the low temperature limit (i.c. T = 0 K), find
the Fermi energy E, in units of eV. You may assume m* to be equal to the free electron mass m
Silicon atoms with a concentration of 7x 1010 cm are added to gallium
arsenide GaAs at T = 400 K. Assume that the silicon atoms act as fully ionized dopant atoms and
that 15% of the concentration added replaces gallium atoms to free electrons and 85% replaces
arsenic to create holes. Use the following parameters for GaAs at T = 300 K:
N. = 4.7 x 1017cm-3 and N, = 7 x 1018 cm-3. The bandgap is E, = 1.42 eV and it is constant
over the temperature range.
