What is the function of semiconductor?
A semiconductor can help controlled flow of electricity. The basic function of such a device is to switch ON and OFF the flow of electricity as and when required. A semiconductor device can perform the function of a vacuum tube with hundreds of times its volume.
What is N and P type semiconductor?
The term p-type refers to the positive charge of a hole. As opposed to n-type semiconductors, p-type semiconductors have a larger hole concentration than electron concentration. In p-type semiconductors, holes are the majority carriers and electrons are the minority carriers.
What is p and n type materials?
p-type and n-type materials are simply semiconductors, such as silicon (Si) or germanium (Ge), with atomic impurities; the type of impurity present determines the type of the semiconductor.
What is difference between n type and p type semiconductor?
In N-type semiconductor, electrons are majority carriers and holes are minority carriers. In P-type semiconductor, holes are majority carriers and electrons are minority carriers. It has Larger electron concentration and less hole concentration. It has Larger hole concentration and less electron concentration.
What is N type semiconductor with example?
The n-type semiconductor examples are Sb, P, Bi, and As. These materials include five electrons in their outer shell. The four electrons will make covalent bonds using the adjacent atoms and the fifth electron will be accessible like a current carrier. So that impurity atom is called a donor atom.
What is undoped semiconductor?
An intrinsic(pure) semiconductor, also called an undoped semiconductor or i-type semiconductor, is a pure semiconductor without any significant dopant species present. The number of charge carriers is therefore determined by the properties of the material itself instead of the amount of impurities.
What is semiconductor with diagram?
Semiconductors are the materials which have a conductivity between conductors (generally metals) and non-conductors or insulators (such as ceramics). Examples of Semiconductors: Gallium arsenide, germanium, and silicon are some of the most commonly used semiconductors.
What is the net charge on 1 N-type semiconductor?
The electrons and holes generated in pairs due to thermal energy are also balanced by their equal and opposite charge. Thus, the net charge will be zero. The situation with regard to P-type semiconductor is also similar. Therefore, an N-type or a P-type semiconductor is electrically neutral.
