In addition to reading the questions and answers on my site i would suggest you to check the following on amazon as well.

At room temperature an intrinsic semiconductor has.

A hole attracts electrons as it is positively charged. Fewer than 1 billion. None of the above. Multiple choice questions and answers on semiconductor theory.

The intrinsic carrier density at room temperature in ge is 2 37 10 19 m 3 if the electron and hole mobilities are 0 38 and 0 18 m 2 v 1 s 1 respectively calculate the resistivity. When an electron leaves the valence band it creates a vacancy known as hole. Suppose an intrinsic semiconductor has 1 billion free electrons at room temperature. At room temperature i e 300 k a semiconductor made of gallium arsenide gaas has an intrinsic electron concentration ni of 1 8 10 6 cm 3 an electron mobility μe of 8500 cm 2 v 1 s 1 and a hole mobility μh of 400 cm 2 v 1 s 1.

The electrical conductivity of intrinsic semiconductors can be due to crystallographic defects or electron excitation. At room temperature 3 0 0 k e l v i n the electrons in the valence band are moved to the conduction band. 4 8 1 0 2 0 m 3 then the concentration of holes in the semiconductor is. An external voltage source is applied to a p type semiconductor.

A calculate the intrinsic electric conductivity and resistivity of gaas at 300 k. If the donor concentration level is 0. In an intrinsic semiconductor the number of electrons in the conduction band is equal to the number of holes in the valence band. If the temperature changes to 75 c how many holes are there.

An intrinsic semiconductor has some holes in it at room temperature. 6 1 0 1 6 m 3. A crystal of intrinsic silicon at room temperature has a carrier concentration of 1. At room temperature an intrinsic semiconductor has a a few free electrons and holes b many holes c many free electrons d no holes e none of the above.

An example is hg 0 8 cd 0 2 te at room temperature. Thus to make it conductive a small amount of suitable impurity is added to the material. An intrinsic semiconductor is capable to conduct a little current even at room temperature but it is not useful for the preparation of various electronic devices. 4 the hall coefficient of certain silicon specimen was found to be 7 35 10 5 m 3 c 1 from 100 to 400 k.

What causes these holes.
