8400 series AC/DC Hall effect testing system

There are many new types of semiconductors and electronic materials being developed and applied today, including optoelectronic materials (solar cells), thermoelectric materials, new display technologies, organic materials, and high-power devices. These materials have electronic properties and are becoming increasingly difficult to measure. In fact, current electronic transport measurement systems for DC magnetic fields cannot measure many of these materials due to their low mobility electronic properties and the need for high-power devices to characterize their characteristics under high temperature conditions. Therefore, these materials are looking forward to a new testing method for characterization.

Product Introduction

Traditional direct current magnetic field measurement technology is effective for measuring migration rates higher than 1cm²/The material of Vs is already sufficient. However, characterizing the low mobility of optoelectronic (solar cells), thermoelectric, and organic electronic materials is difficult. Extracting very small Hall voltages from the background noise generated by such materials using direct current magnetic field technology is a challenge, which can lead to poor measurement repeatability and stability. In order to compensate for the shortcomings of traditional DC magnetic field measurement technology in measuring low mobility materials, Lake Shore and Joyo have established a cooperative relationship. This collaboration gave birth to the 8404 Hall effect measurement system, which has an AC magnetic field Hall measurement option and the ability to measure migration rates as low as 0.001 cm²/Vs， Customers can easily measure low mobility materials.

The Hall effect measurement of Lake Shore 8404 in the United States adopts the van der Waals method for sample testing, which is a very sound measurement platform. The measurement options include: AC magnetic field option, low temperature option, high temperature option, high resistance option, low resistance option, optical channel option, and gate voltage option. When your material measurement needs to change, you can add new options as needed.

• The Hall effect measurement technology of Lake Shore 8404 in the United States combines direct current magnetic field and alternating current magnetic field, and is therefore widely used in scientific research fields. As an optional variable temperature component and measurement module, it can meet various needs of users and can be selected according to actual applications.

  
  

  Optoelectronic and thermoelectric materials

  The main characteristic of optoelectronic (solar cells) and thermoelectric materials is their low mobility, so conventional DC magnetic field Hall effect measurement methods cannot characterize these materials. The 8404 Hall effect plus AC magnetic field measurement option can be used to easily test these materials.

• organic materials

  The mobility of organic electronic devices is very low, and the 8404 Hall effect provides an opportunity for measurable organic electronic devices. These organic electronic materials are the basis for printed and flexible electronic devices, organic light-emitting diodes, and organic solar cell materials.
