Answer
$70.1$%
$2.2$%
$92.3$%
$18.3$%
$55.5$%
Work Step by Step
According to equation 2.16, we have:
for MgO, $X_{Mg}=1.3$ and $X_{O}=3.5$
%$IC=[1-exp(-0.25)(3.5-1.3)^2]\times100=70.1$%
for GaP, $X_{Ga}=1.8$ and $X_{P}=2.1$
%$IC=[1-exp(-0.25)(2.1-1.8)^2]\times100=2.2$%
for CsF, $X_{Cs}=0.9$ and $X_{F}=4.1$
%$IC=[1-exp(-0.25)(4.1-0.9)^2]\times100=92.3$%
for CdS, $X_{Cd}=1.5$ and $X_{S}=2.4$
%$IC=[1-exp(-0.25)(2.4-1.5)^2]\times100=18.3$%
for FeO, $X_{Fe}=1.7$ and $X_{O}=3.5$
%$IC=[1-exp(-0.25)(3.5-1.7)^2]\times100=55.5$%
