The definitions of conductor, insulator, semiconducting elements, donor impurities, acceptor impurities, n -type semiconductors, p -type semiconductors are to be described. Concept introduction: On the basis of extent of movable free electrons in the material, these materials are classified into conductors, insulators, or semiconductors. The materialsthat conduct electricity are called conductors. The materialsthat do not conduct electricity are called insulators. The material that has conductivity between insulators and conductors are semi-conductors. The elementsthat, when added to a semiconductor, provide unbound or free electrons to the semiconductor that may serve as current carriers are termed as donor impurities. The materialsthat, when added to a semiconductor, can form p -type region by creating positive charges or holes are termed as acceptor impurities. The material in which holes are the majority carriers and electrons are the minority carriers is called p -type semiconductors. The material in which electrons are the majority carriers and holes are the minority carriers is called n -type semiconductors. Semiconductors are further classified as n -type and p -type semiconductors.

Modern commercial airliners are largely made of aluminum, a light and strong metal. But the fact that aluminum is cheap enough that airplanes can be made out of it is a bit of historical luck. Before the discovery of the Hall-Héroult process in 1886 , aluminum was as rare and expensive as gold. What would happen if airplanes had to be made of steel? The fuselage of the Airbus A380, which can carry 575 passengers, is approximately a hollow aluminum cylinder without ends, 72.0m long, 8.4m wide, and 2.5mm thick (see sketch at right). The fuselage of an airplane Suppose this fuselage was made of steel (density 7.87/gcm3 ) instead of aluminum (density 2.70/gcm3 ), and let's say the average passenger has a mass of 83kg . We'll also assume the engines can't lift any greater mass than they already do. Calculate the number of passengers that the Airbus A380 could carry if its fuselage was made of steel.
