TYPE:Hopi ear type sensor

1. Hopi ear effect

Semiconductor or metal foil is placed in a magnetic field, when the current ( and a magnetic field perpendicular to the direction of flow of thin plane ), in a direction perpendicular to the magnetic field and current direction generated electromotive force, this phenomenon is known as the Hopi ear effect.

2. Hopi ear element

At present the commonly used Huo ear material germanium, silicon ( Ge ) ( Si ) ( InSb ), indium antimonide, indium arsenide ( InAs ) etc.. N type germanium and easy processing and manufacture, Huo ear coefficient, temperature performance, good linearity; P type silicon linearity best, Huo ear coefficient, temperature performance with N type germanium, but a lower electron mobility, with a load capacity is poor, usually not for a single Hopi ear element.
