a range of compact bench top design Hall Effect measurement systems. The compact design and low cost makes
this the ideal R&D lab or university tool for measuring the Hall Effect. Here are some of the features of
the HMS-3000 model:
- Low and high resistivity measurement capability, bulk
and sheet carrier concentration and mobility, Hall coefficient in semiconductors
- DC measurement modes
- van der Pauw and Hall Bar
- Board system (room temperature or
The HMS-5000 Hall Effect
Measurement System has automated magnet movement, with variable temperature capability and powerful analysis
software. The system is automated so that without user intervention, it will ramp to each user defined
temperature, stabilize, make the measurement (including moving the magnet automatically), and then plot a
variety of temperature dependent material properties.
The system plots
concentration versus temperature, mobility versus temperature, resistivity versus temperature, conductivity versus
temperature, and Hall coefficient versus temperature. The systems provides the test results as tabular data as well
as in graph form. The user defines the desired temperature steps within the range of 80K to 350K, fills the two LN2
reservoirs, and then the system automatically applies and switches the input current,
measures the voltages, changes temperature, and moves the magnets all without user intervention. Once the test is
finished, all of the temperature dependent graphs and tabular data are ready for viewing.
The systems can be
used to characterize various materials including all semiconductors including Si, SiGe, SiC, GaAs, InGaAs, InP, GaN
(N Type & P Type can be measured), metal layers, oxides, etc. Sample testing can be performed to demonstrate
the system's capability.
Test with variable temperature from 80K up to
Motor controlled magnet moves
Testing of Temperature vs carrier density,
mobility,resistivity, hall coefficient, conductivity, etc.
Easy to use with powerful results
Very competitive price The Ecopia HMS-5000 variable
Temperature (80K to 350K) system offers all of the above features with the enhanced capability of the
increased variable temperature range.
