The PDL Hall system from Semilab is designed to handle AC and DC Hall measurement modes. The AC field measurement is mainly for materials that have a mobility of less than 0.1 cm2/Vs, which is a benefit when compared to the DC field measurement mode. Materials with such characteristics are typically photovoltaic, semiconductor, or thermoelectric materials.
Key Features
- Simple and strong tabletop system design
- Can measure a broad range of mobilities, including very low mobilities and semi-insulating samples; has the capability to carry out alternating (AC) as well as traditional static field (DC) Hall measurements
- Tabletop arrangement, utilizing rotating Parallel Dipole Line magnets (bulky electromagnet not necessary)
- Cooling system is not required
- Software extracts low Hall signal using software-based lock-in detection (thus avoiding the need for expensive hardware-based lock-in detection)
- Software-regulated measurement and automated parameter extraction
