What is doping in conductor?

The process of adding suitable impurities in the intrinsic semiconductor is called doping. The impurity added to the intrinsic semiconductor to increase its conductivity is called dopant. There are some methods of doping in case of a conductor.impurity atoms can be added to the intrinsic semiconductor in different ways discussed below:A very small quantity of impurity atoms is made by diffusing into the high purity molten material such as germanium when the crystal is grown out of melt.Impurity atoms can also be added into the intrinsic semiconductor by heating it in the environment having impurity atoms.Impurity atoms can also be added into the intrinsic semiconductor by bombarding it with the impurity atoms.


Why suitable impurities are added to semiconductor depending upon its use?

The idea is that, depending on the impurities added, the semiconductor will be of one of two different types: * n-type, where the current is conducted by electrons, and * p-type, where the current is conducted by holes.


Why intrinsic conductor not used in electronic devices?

Intrinsic semiconductors have small conductivity at the room temperature. and also if we raise the temperature to increase their conductivity then they will start acting merely like a conductor. and there will not be any control over the directions or the magnitude of the current flowing through it. so by mixing the suitable impurity(dopant) we obtain the extrinsic semiconductor. so that the conductivity as well as the control over the current can be increased. Although intrinsic semiconductor are also somwhere used in electronics where i high resistance layers or a separation layers b/t two systems is needed. like in PIN diode.

The game lines is suitable for which age groups?

The game lines is suitable to ages 10 years old and up. The suggested age groups are because the game has elements of strategy more suitable to older children and adults.


Which of these four radioactive elements would you choose to date a fossil from the most recent epoch?

Four elements are not mentioned but fossils contain organic material that means carbon compounds so carbon-13 isotope is more suitable, in case of radioactive elements that isotope is most suitable which have the half life period in millions of years.
