Hall Effect Measurement System - AC / DC Field - PDL-1000

Semilab’s PDL Hall system is suitable for both AC and DC Hall measurement modes. The AC field measurement can be performed on materials with a mobility of less than 0.1 cm2/Vs, which can be superior to the DC field measurement mode.

In general, materials with such characteristics are thermoelectric, photovoltaic ( aSi CIGS  Perovskite) , Organics Electronics ( OTFT, OLED), Transparent conductive oxides TCO( ITO, AZO, ZnO, IGZO) and  semiconductor materials.

High Sensitivity Parallel Dipole Line Hall Measurement. AC/DC Field

Features

  • Simple and sturdy tabletop system design
  • A broad range of mobilities, such as semi-insulating samples and very low mobilities (<0.1 cm2/Vs)  can be measured, including the ability to carry out both conventional static field (DC) and alternating (AC) Hall measurements
  • Tabletop arrangement, using rotating Parallel Dipole Line magnets (bulky electromagnet not required)
  • Background illumination option
  • Software retrieves low Hall signal with the help of software-based lock-in detection (this avoids the need for expensive hardware-based lock-in detection)
  • Software-regulated measurement and automated parameter extraction
  • Cooling system is not required
  • Compact design
  • Easy operation
  • High sensitivity (ability to handle mobility <0.1 cm2/Vs)
  • Uniformity (<2% sample size up to 10×10 mm)
  • Large magnetic field (approximately 2.5 T pk-pk)
  • Proprietary signal processing and user interface (UI) software
  • Optional gate bias voltage
