The HMS-3000 includes software with I-V curve capability for checking the ohmic integrity of the user made sample contacts. The systems can be used to characterize various materials including semiconductors and compound semiconductors (N Type & P Type) such as Si, Ge, SiGe, SiC, GaAs, InGaAs, InP, GaN, ZnO, TCOs, metals, etc., at both 300K and 77K (room temperature and liquid nitrogen temperature). Van der Pauw Ecopia HMS-3000 Hall Measurement System

Main Body (HMS-3000)

Characteristics

  • Compact Desktop Model – Permanent magnets and a small circuit system are used instead of an electric magnet system and a bulky constant current source, producing a compact, desktop design.

Simplicity and Accuracy

  • 5 Stage current ranges reduce the allowance error to a minimum.Simple Operation – Speedy Data Results
  • Data is input by a simple operation providing bulk/sheet carrier concentration, mobility, Hall coefficient, bulk resistivity, conductivity, magnetoresistrance, and alpha (Vertical/Horizontal ratio of resistance).

Low Temperature Measurement System (77K, 300K)

The SPCB-1 Spring Clip Board does not require the usual sample bonding process invoving the use of small wires.The Spring Clip Board is for use with the 0.55 Tesla magnet kit (not the 1.0T) and it has spring loaded clips and spring loaded tips to make contact without using bonding wires. (When using the Spring Clip Board, usually the contacts must still be annealed with a conductive material such as indium to insure good probe contact)
