Conduction of Electricity in Pure Crystal of Silicon at Room Temperature

The correct statement about the conduction of electricity in a pure crystal of silicon at room temperature is:

d) The conduction is due to the movement of both the electrons released and holes formed.

Explanation:

Conduction of electricity in a pure crystal of silicon at room temperature occurs due to the movement of both the electrons released and holes formed. This is because silicon is a semiconductor, and its electrical conductivity lies between that of conductors and insulators.

Electrons present in the fully occupied lowest energy states cannot conduct electricity as they are tightly bound to their respective atoms. Some electrons are capable of leaving the bonds at room temperature, but they cannot conduct electricity alone. This is because they leave behind positively charged holes in the lattice, which can conduct electricity by accepting electrons from neighboring atoms.

Thus, the movement of both the electrons released and holes formed is necessary for the conduction of electricity in a pure crystal of silicon at room temperature.

Conclusion:

In conclusion, the correct statement about the conduction of electricity in a pure crystal of silicon at room temperature is that it occurs due to the movement of both the electrons released and holes formed. This is because silicon is a semiconductor with a conductivity lying between that of conductors and insulators.

Similar Class 12 Doubts

Read the following text and answer the following questions on the basis of the same:At power plant, a transformer increases the voltage of generated power by thousands of volts so that it can be sent of long distances through high-voltage transmission power lines. Transmission lines are bundles of wires that carry electric power from power plants to distant substations. At substations, transformers lower the voltage of incoming power to make it acceptable for high volume delivery to nearby end-users. Electricity is sent at extremely high voltage because it limits so-called line losses. Very good conductors of electricity also offer some resistance and this resistance becomes considerable over long distances causing considerable loss.At generating station, normally voltage is stepped up to around thousands of volts. Power losses increase with the square of current. Therefore, keeping voltage high current becomes low and the loss is minimized. Another option of minimizing loss is the use of wires of superconducting material. Super-conducting materials are capable of conducting without resistance, they must be kept extremely cold, nearly absolute zero, and this requirement makes standard superconducting materials impractical to use. However, recent advances in superconducting materials have decreased cooling requirements. In Germany recently 1 km of superconducting cable have been installed connecting the generating station and the destination. It has eliminated the line loss and the cable is capable of sending five times more electricity than conventional cable. Using superconducting cables Germany has also get rid of the need of costly transformers. Transformers generate waste heat when they are in operation and oil is the coolant of choice. It transfers the heat through convection to the transformer housing, which has cooling fins or radiators similar to heat exchangers on the outside. Flush point is a very important parameter of transformer oil. Flashpoint of an oil is the temperature at which the oil ignites spontaneously. This must be as high as possible (not less than 160° C from the point of safety). Fire point is the temperature at which the oil flashes and continuously burns. This must be very high for the chosen oil (not less than 200° C).Oil transfers heat from transformer winding by the process of

Products of electrolysis depend on the nature of material being electrolysed and the type of electrodes being used. If the electrode is inert (e.g., platinum or gol d), it does not participate in the chemical reaction and acts only as source or sink for electrons. On the other hand, if the electrode is reactive, it participates in the electrode reaction. Thus, the products of electrolysis may be different for reactive and inert electrodes. Aqueous copper sulphate solution and aqueous silver nitrate solution are electrolysed by 1 ampere current for 10 minutes in separate electrolytic cells. In these questions, a statement of assertion followed by a statement of reason. Choose the correct answer out of the following choices.Assertion (
