Cochran, A d v. Merten, 2. Barker, Phys. Cochran and R. Cowley, J. Solids 23, This applicability of the LST relation undoubtedly results because the measured quantities represent the effective renormalized responses for the crystal.

The LST relation played a prime role in the early development of the soft mode theory offerroelectricity. The soft FE mode should then vary with T as indicated by Eq. This has now been confirmed experimentally for many displacive ferroelectrics.

Solid State Chemistry

Experimentally, it is observed that essentially all of the temperature dependence of the phonons is associated with that of w,, so that Eq. In some crystals as the frequency of the soft mode changes, it may couple directly with other phonon modes of the crystal. Alternatively, the soft mode itself may be a coupled mode involving two or more fundamenG.

Samara, Phys. Samara and B. Morosin, Phys. B: Solid Sture [3] 8, Fleury and J. Worlock, Phys. It is necessary to consider these interactions explicitly in the analysis of inelastic light and neutron scattering from such coupled systems.

Similarly, interactions of the soft optic mode with other optic modes are important in SbSI, whereas in KH2P04 and its isomorphs the soft mode is a coupled excitation between the proton motion and an optic mode of the lattice, and this excitation further couples to an acousitc mode near T,, As will become clear later, pressure has been an important variable in understanding these coupled-mode interactions.

Several different types of coupled-mode systems have been investigated in different materials with different theoretical treatments given for has shown that the various types of each type of interaction.

These expressions can be readily extended to include more than two interacting modes by extending the sum in Eq.

Such an extension was used by Lagakos and CumminsMto investigate the interaction of the lower-frequency branch of the coupled proton tunneling-optic mode system in KH2P04with an acoustic mode.

Scott, in "Light Scattering in Solids" M. Balkanski, ed. Flammarion 36 Sciences, Paris, Lagakos and H. Curnmins, P h y s. B: Solid State [3] 10, An additional constraint is required to obtain a unique form for the interaction. The form of the interaction is therefore based on the particular model with which one wishes to compare the measurements. Evidence for this behavior has been observed. This and a variety of other important pressure effects are dealt later in this review. For diatomic crystals, the result, often referred to as the LST relation, is 2.

The result is where the product is over all the optic branches of the dispersion curves. Although it is based on the R. Lyddane, R.

Such an extension was used by Lagakos and CumminsMto investigate the interaction of the lower-frequency branch of the coupled proton tunneling-optic mode system in KH2P04with an acoustic mode. On beating, it loses oxygen and turns yellow. Transition metals exhibit this defect, e. Their conductivity is due to the presence of impurities. They are formed by doping. It is defined as addition of impurities to a semiconductor to increase the conductivity.

The conductivity is due to the presence of positive holes. CdSe and HgTe. These are weakly repelled by the magnetic field and do not have any unpaired electron, e.

These are attracted by the magnetic field and have unpaired electrons These lose magnetism in the absence of magnetic field, e. These are attracted by the magnetic field and show permanent magnetism even ill the absence of magnetic field e.

These substances have net magnetic moment zero due to compensatory alignment of magnetic. These substances have a net dipole moment due to unequal parallel and anti-parallel alignment of magnetic moments, e.

Class 7. Class 8. Class 9. Class The Solid State Solids Solids are the chemical substances which are characterised by define shape and volume, rigidity, high density, low compressibility.At high temperature we rewrite Eq. The solid state provides challenging opportunities for illustrating and applying principles of chemistry to systems of academic interest and technological importance.

This fact was recognized in the original soft-mode treatments of Cochran,1. Thus far our discussion has dealt implicitly with the behavior of the soft mode in the high-temperature phase. Chapter 3 - Electrochemistry.
