Analysis of the electrical characteristics of Hall elements made of Germanium and Gallium Arsenide

Hall elements are among the most widely used magnetic sensing components in electronics, finding applications in various fields depending on the material they are made of - such as silicon, gallium arsenide, germanium, and others. To choose the optimal sensor for a specific application, it is essential to understand the parameters of different materials. Properly selecting the sensor not only facilitates the design of various systems but also significantly enhances the application’s efficiency by providing more accurate and reliable results. This selection process is key to the successful implementation of magnetic sensing devices and systems in any industry. The automated DX50 system, which is used, significantly streamlines engineers’ work by providing values for various parameters such as Hall coefficient and voltage, carrier mobility, resistivity, and others. Calculations are based on the Van der Pauw method, ensuring high data accuracy. This measurement system greatly reduces the time required for measurements and decreases the likelihood of error in measurement and calculation, providing more reliable and accurate results.
