Assuming that the charge carriers are electrons that have a mobility of 0. An electromagnetic wave of free space wavelength 0. Calculate the mobility. What is your criterion? If both electrons and holes are present the conductivities, add.

The measured conductivity 0. Calculate the mobilities. Measurements on sodium have provided the following data: resistivity 4. Calculate i the density of electrons, ii the mobility, iii the effective mass, iv the collision time, v the number of electrons per atom available for conduction.

About this book

Electric conduction in sodium is caused by electrons. The number of atoms in a kg mole is 6.

For an electromagnetic wave propagating in sodium plot the real and imaginary part of the wave number k as a function of frequency use a logarithmic scale from to Hz. Use the conductivity and the collision time as obtained from example 1.

A magnetic field can be applied parallel to this face. A current of 5 mA is passed between the end contacts when a voltage of mV is applied. This generates a voltage across the point contacts of 3. The Hall effect see Fig.

Under the effect of the magnetic field both carriers are deflected in the same transverse direction. Obviously, no electric field can stop simultaneously both the electrons and the holes, hence whatever the Hall voltage there will always be carrier motion in the transverse direction.

Does this mean that there will be an indefinite accumulation of electrons and holes on the surface of one of the boundaries? If not, why not? Derive an expression for the Hall coefficient RH [still defined by eqn 1.

The experimentally determined Hall coefficient is found to be negative. Can you conclude that electrons are the dominant charge carriers?

Hint: Write down the equation of motion neglect inertia for both holes and electrons in vectorial form. Resolve the equations in the longitudinal z-axis in Fig. Neglect the product of transverse velocity with the magnetic field.

Find the transverse velocities for electrons and holes. Find the transverse current, and finally find the transverse field from the condition that the transverse current is zero.

At best, they are abandoned. The second edition of "Electronic Properties of Materials" has been in use now for about seven years. During this time my publisher gave me ample opportunities to update and improve the text whenever the Ibook was reprinted. There were about six of these reprinting cycles.

Electrical Properties of Materials (8th edition)

Eventually, however, it became clear that substantially more new material had to be added to account for the stormy developments which occurred in the field of electrical, optical, and magnetic materials. In particular, expanded sections on flat-panel displays liquid crystals, electroluminescence devices, field emission displays, and plasma dis. Magnetic storage devices also underwent rapid development.

Of course, the entire text was critically reviewed, updated, and improved.

If today's students do not learn to utilize it, another generation is "lost" on this matter. In other words, it is important that students become comfortable with SI units.The wave is what one calls a slow wave since it is to the right of the light line, having a phase velocity always below that of light.

What shall we do? Thermal Expansion. This book on electrical, optical, magnetic, and thermal properties of materials differs from other introductory texts in solid-state physics.
