## Resource summary

CONCEPT MAP OF SOLID STATE OF PHYSICS
1 PROPERTIES OF SOLIDS
1.1 ELECTRICAL PROPERTIES
1.1.1 Models Of electrons in Solids
1.1.1.1 Band theory of solids
1.1.1.2 Quantum free electron theory
1.1.1.3 Classical free electron theory

Annotations:

• Here electron stay as according to the kinetic theory of ideal gases.
1.1.1.4 Konig-Penny model
1.2 STRUCTURAL PROPERTIES
1.2.1 Crystal structures & inter atomic bonding
1.2.1.1 Crystalline materials

Annotations:

• We can find three types of solids. 01)Crystals 02)Poly crystals 03)Amorphous Here we consider the crystalline materials.
1.2.1.2 Lattices
1.2.1.2.1 Bravias Lattice

Annotations:

• We can find the Simple cubic,Face centered cubic,Body centered cubic forms of these lattices. There are 14 Bravias Lattices which of seven crystal systems
1.2.1.2.1.1 2D
1.2.1.2.1.2 3D
1.2.1.2.1.2.1 cubic
1.2.1.2.1.2.2 Tetrogonal
1.2.1.2.1.2.3 Ortorhombic
1.2.1.2.1.2.4 Hexagonal
1.2.1.2.1.2.5 Trigonal
1.2.1.2.1.2.6 Monlinic
1.2.1.2.1.2.7 Triclinic
1.2.1.2.2 Non-Bravias lattices
1.2.1.3 Crystal planes & Miller Indices

Annotations:

• Miller indices are introduced as 1/h,1/k,1/l in the theories,which by the means h,k,l are the planes of the crystal
1.2.1.4 Reciprocal Space & Reciprocal Lattice
1.2.1.5 Importance of solid state matter

Annotations:

• Of course it is an practical incident explaining part of science,physics in nature.
1.2.1.6 Crystal structures
1.2.1.6.1 Diamond
1.2.1.6.2 NaCl
1.2.1.7 Crystal symmetry

Annotations:

• We can find several symmetries of the crystals like horizontal,vertical,diagonal &amp; etc
1.2.2 Difffraction methods & crystal structure determination

Annotations:

• This can be shown by the experiments used in the optics lab.All the 2dSinQ=L gives the relationship of the interferences.Inteferences are of constructive &amp; destructive
1.2.2.1 Neutron Diffraction
1.2.2.2 Electron Diffraction
1.2.2.3 Applications of X-ray Diffraction
1.2.2.4 Experimental methods of X- ray Diffraction
1.2.3 Thermal properties of Solids
1.2.3.1 Debye theory
1.2.3.2 Einstein's theory
1.2.3.3 classical theory
1.2.4 Lattice vibrations & Phonons

Annotations:

• Phonons are vibrational energy packets
1.2.4.1 Model Inter - Atomic potential

Annotations:

• Inter - atomic potential consist of the attractive &amp; the repulsive energy of a molecule. It is inversely proportional to the certain power of the distance between the atoms contributing to the bond
1.2.4.2 Cohesive energy crystal

Annotations:

• Cohesive energy is the binding energy or the energy difference of free atoms &amp; the energy of the molecule made by the free atoms
1.2.4.3 Cohesive energy for Vander-Waals solids
1.2.4.4 Bonding in Solids

Annotations:

• Bondings are ionic,co-valent,metalic,Vander-Waals or else London,Hydrogen &amp; etc.
