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

Semilab’s PDL Hall system is suitable forboth 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.

Operation of the magnets

PDL-1000 setup and sample holder

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
