2.5 Bonding Forces and Energies<br />

• A number of material properties depend on E o ,<br />

the curve shape, and <strong>bonding</strong> type<br />

– Material with large E o typically have higher melting<br />

points<br />

– Mechanical stiffness is dependent on the shape of its<br />

force vs. interatomic separation curve (F vs r)<br />

– A material’s linear coefficient of thermal expansion<br />

is related to the shape of its E vs. r curve
