A semiconducting crystal 12mm long, 5mm wide and 1mm thick has a magnetic flux density of 0.5Wb/m2 applied from front to back perpendicular to largest faces. When a current of 20mA flows length wise through the specimen, the voltage measured across its width is found to be 37μV. What is the Hall coefficient of this semiconductor?

Semiconductors topics include: Free electron theory, semiconductors properties and classification, hall effect, solar cell, p-n junction characteristics, zener diode, rectifier, led and transistors. Semiconductors are materials with electrical properties that fall between conductors and insulators. They can be pure elements, like silicon or germanium, or compounds, like gallium arsenide or cadmium selenide.  Semiconductors are the foundation for electronics, especially computers.

Semiconductors are materials with electrical properties that fall between conductors and insulators. They can be pure elements, like silicon or germanium, or compounds, like gallium arsenide or cadmium selenide. 

Semiconductors are the foundation for electronics, especially computers. They are smaller in size, take up less space, and use less power than vacuum tubes. Because they can be made so small, electrical devices can be made thin and lightweight without compromising processing power. 
A crucial property of semiconductors is the band gap, which is a range of forbidden energies within the material's electronic structure. 
In 1874, Karl Braun discovered and documented the first semiconductor diode effect. In 1901, the first semiconductor device, called "cat whiskers," was patented.
