Featuring patented* FastHall technology, the M91 fundamentally changes Hall effect characterization by eliminating applied magnetic field polarity switching. This results in faster, more accurate measurements, especially with high field superconducting
magnets or low mobility materials.
Backed and supported by nearly two decades of expertise in materials characterization systems, Lake Shore’s fully integrated Hall effect measurement systems (HMS) are used to characterize physical properties in semiconductors, as well as
other electronic materials including magnetoresistors, multilayer magnetic films, dilute magnetic semiconductors, superconductors, and spintronics devices. Available in a variety of electromagnet-based configurations ranging in field up to
2 T or a powerful 9 T superconducting magnet-based configuration, Lake Shore HMS are ideally suited for the most demanding materials research applications, product development, and quality control. An assortment of options expands the functionality
of Lake Shore HMS.
Modern materials ranging from compound semiconductors to nanomaterials are pushing the limits of transport measurements. Lake Shore combines precision electronics, flexible software, variable magnetic field and temperature, and a wide resistance
range into the most advanced HMS. When used in combination with data taken from the variable field Hall measurement, our proprietary Quantitative Mobility Spectrum Analysis (QMSA®) software resolves individual carrier mobilities and densities
in multi-carrier devices such as quantum wells and high electron mobility transistors (HEMTs).
Please note: the AC measurement option is no longer available for the 9700A
