UKPCS Science: Conductors, semiconductors and insulators(2) #32

Oracle IAS, the best coaching institute for UPSC/IAS/PCS preparation in Dehradun brings to you UKPCS Science (paper #6).

Semiconductor materials

Elements that are used as semiconductors, such as silicon and germanium, have four outer shell electrons. This means that they can form four bonds with other identical atoms.

In a crystal of pure silicon each silicon atom is surrounded by four other silicon atoms. In this state the silicon will not conduct.

Pure silicon can be doped by tiny quantities of impurities by diffusing the impurities as a gas into the liquid semiconductor before it crystallizes. If an impurity element with five outer shell electrons, such as arsenic, is added to silicon in small quantities, (approximately one impurity atom to every one million silicon atoms), the impurity atoms will fit into the crystal structure but there will be one electron not bonded into the valence band of the crystal. This free electron is a charge carrier able to move within the conduction band.

This impurity causes the material to conduct and is called n-typesilicon.

UKPCS Science: Telescope #30

Oracle IAS, the best coaching institute for UPSC/IAS/PCS preparation in Dehradun brings to you UKPCS Science (paper #6).

A telescope is an important tool for astronomy that gathers light and directs it to a single point. Some do this with curved mirrors, some with curved lenses, and some with both. Telescopes make faraway things look bigger, brighter and closer. Galileo was the first person to use a telescope for astronomy, but he did not invent them. The first telescope was invented in the Netherlands in 1608. Some telescopes, not mainly used for astronomy, are binoculars, camera lenses, or spyglasses.
