    1.1 CRYSTALLINE AND AMORPHOUS SOLIDS On the basis of structure, solids may be divided into two broad categories – crystalline and amorphous. In crystalline solids, the atoms are stacked in a regular manner, forming a three-dimensional pattern which may be obtained by a three-dimensional repetition of a certain pattern unit.

    2.1 CHOICE OF X-RAYS, ELECTRONS AND NEUTRONS FORCRYSTAL STRUCTURE DETERMINATION The interatomic spacing in crystals is of the order of 1 Å. To explore the structure of crystals, we require de Broglie waves, which when incident on solids, interact with its atoms. For this, we need wavelengths of the incident waves to be comparable with the interatomic spacing; visible or ultraviolet light (l ~ 5000 Å) cannot be used because it would not be able to provide the resolution necessary for this purpose.

    3.1 WHAT IS AN IMPERFECTION? The concept of an ideal crystal with a perfect arrangement of atoms is, strictly speaking, valid only at the absolute zero temperature because then there is no entropy contribution. However, at a finite temperature, a certain native configurational disorder is introduced into the structure (a direct consequence of laws of thermodynamics) and solid becomes structurally imperfect.

    Bonding in Solids Price 2.99  |  2.99 Rewards Points

    4.1 INTRODUCTION In any solid, the mutual interatomic forces are basically electrostatic in nature, and the primary differences among different types of solids depend on the ways in which the valence electrons of the constituent elements are distributed, i.e. it depends on the type of bonding. Thus, on the basis of bonding type, we have the following five categories of solids:

    Lattice Vibrations and Thermal Properties Price 2.99  |  2.99 Rewards Points

    5.1 PHONONS As a result of their thermal motion, the lattice ions in a solid vibrate about their equilibrium positions. All the elastic properties, compressibility and propagation of acoustic waves in solids are then described in terms of a continuum theory disregarding the atomic structure of the lattice.

    6.1 DRUDE’S MODEL During the nineteenth century, there was no precise concept known for atomic structure. The electron was discovered by Thomson in 1897, and this discovery had a vast and immediate impact on theories of structure of matter. Three years later (i.e. in 1900) Drude gave his theory of electrical and thermal conduction by considering the metals to be containing free electrons, and thereby applying the kinetic theory of gases to metals

    Band Theory Price 2.99  |  2.99 Rewards Points

    There are two approaches to discuss formation of energy bonds in solids: (i) atomistic approach and (ii) one-electron approach. In the atomistic approach, electrons are assumed to be tightly bound to individual atoms. As atoms are brought together to form a crystal, interaction between the neighbouring atoms causes the electron energy levels of individual atoms to spread into bands of energies.

    8.1 FREE -ELECTRONS In case of one-electron model, we may ignore the interactions between the valence electrons and the (Hartree or Hartree–Fock) potential V(rÆ) seen by each valence electron, as it moves through the crystal may be taken as constant. The electrons are then described by plane-wave states

    9.1 CONDUCTOR, INSULATOR AND SEMICONDUCTOR A conductor is any material that will support a generous flow of charge when a voltage source of limited magnitude is applied across its terminals. An insulator is a material that offers a very very low level of conductivity (under pressure) from an applied voltage source. A semiconductor is a material that has a conductivity level somewhere between the extremes of an insulator and a conductor.

    10.1 ORIGIN OF MAGNETIC PROPERTIES OF MATERIALS We know that a small circular current-carrying loop has a magnetic moment associated with it. So motion of electrons in atoms is responsible for magnetism and quantised nature of electronic motion gives rise to the fundamental unit of magnetic dipole moment,

    11.1 INTRODUCTION In insulating materials (dielectrics), electrons are very tightly bound to the atoms (and forbidden gap in the energy band picture is comparatively larger). Consequently, electrons cannot be made free, however they can only be displaced a bit within the molecule (under the application of an external electric field) and their cumulative effect accounts for the characteristic behaviour of dielectric materials

    12.1 THE DISCOVERY Dutch physicist H. Karnerlingh Onnes was successful in liquifying helium in 1908 (nitrogen liquifies at 77.4K). The attainment of liquid He temperatures opened a new regime of low temperatures and it was discovered by him in 1911 (while investigating the electrical properties of frozen mercury) that the electrical resistance of Hg completely disappeared on approaching 4.2 K. It was discovered that the disappearance did not take place gradually, but abruptly.

    Elastic Constants of Crystals Price 2.99  |  2.99 Rewards Points

    13.1 INTRODUCTION Solids are not absolutely rigid: by application of suitable forces, they can be made to change in both size and shape. However, when these changes are not too great, they return to their original size and shape when forces are removed. This property of solids is termed elasticity and is common to all classes of solids.
