4. (a) Explain the concept of (i) intrinsic, (ii) n-type, and (iii) p-type semiconductors with the aid of bond diagrams and band diagrams.
(b) What is a hole? Using a mathematical derivation to show that the holes behave like positive charges.
(c) Explain with the aid of Fermi-Dirac distribution function that at 0° K, all the energy states in the valence band of silicon are filled and all the energy states in the conduction band are empty.
(d) Why it is necessary to use effective mass instead of real mass for electrons in the analysis of semiconductor materials and mention why different effective masses are to be used for different types of semiconductors,
(e) Explain (a) bonding orbital and (b) anti-bonding orbital.
Explain Cellobiose Cellobiose is a dimer of D-glucose, it is hydrolyzed by aqueous acid into two molar equivalents of D- glucose.
what is diagonal relationship?
WHAT IS USE OF ION PAIR REAGENTS? The chemical substances that pair each other, to produces complexes. These can use for stabilization of one of the molecule that is more active
Penta valent element has one electron more than 4 electrons which could be used for conduction while the trivalent elements has 1 electron less , this can also be seen as a hole
In how many chlorines does Slicon bound The sito four chlorines, and is thus tetrahedral. The Cl-Si-Cl bond angle is 109.5°.
The tetrahedral arrangement of four ligands surrounding the metal ion may be visualized. It is clear that in tetrahedral field, none of the orbitals point exactly towards the ligan
Q. Explain Valence Bond Theory? This concept starts with the assumption that the bond between the metal ion and the ligand is basically covalent in nature. In order to form a c
preparation of succinic and oxalic acid
Q. Show the techniques of preservation? The various methods can be used for preservation of foods. Some of the common methods employed to preserve foods are summarized herew
Physical properties of Dihydric alcohols (a) Dihydric alcohols is a colourless, syrupy liquid and sweet in taste. Its boiling point is 197°C. (b) Dihydric alcohols is misci
