Carrier resistivity and mobility measurement system based on the Hall effect HMS 8407 (LakeShore Cryotronics). Ideal for measuring variable temperature resistivity and mobility from 1 to 10⁶ cm²/V·s. Optionally, AC current can be used to extend the mobility measurement range down to 10⁻³–3 cm²/V·s.

Maximum magnetic fields: 2.25 T in DC mode (8407) and 1.31 T in AC mode (8407). Measurements can be performed in the standard resistance range from 0.5 mΩ to 10 MΩ. High-resistance option extends the range to 200 GΩ. Low-resistance option significantly lowers the noise level. The device operates across a wide temperature range, from 15 K to 1273 K. All measurements can be performed at room temperature, elevated temperature (up to 1273 K), or cryogenic conditions (down to 15 K).

Basic services:

• Measurement of carrier mobility, carrier type, and concentration
  
• Measurement of resistivity and the Hall coefficient
  
• Hall voltage measurements
  

Pricing:

• Price for 1 hour of basic analyses on the equipment: 227 PLN/hour. The cost of more complex analyses will be determined individually.
  
• An additional 150 PLN should be added to the analysis cost for preparing a summary report.
