The Model CMM-250 has been designed to measure the electron and hole mobilities which are very critical to evaluation of the thin film to be used for the EL elements and solar cells. The system consists of a short pulse nitrogen excitation die laser for carrier generation, high speed sampling electronics, sample compartment and data processing system. Our noise prevention system and unique signal processing have reduced noise significantly so that fast response such as nano-second order and high detection sensitivity have been achieved in order to measure the electron and hole mobilities. Changing different die ( as an option ) of the die laser enables the system to oscillate the wavelength range from 337nm to 730nm with pulse width shortened in 600 pico second. In addition to this TOF method measurement, the system with an optional unit is capable to measure mobilities by FET method(option).

Features

? Achievement of time resolution at nano-second enables the system to measure mobility such as 10-7-１0-１cm2/V·sec( this maybe changed depending on the sample and its thickness).

? Easy Operation with probe/sample compartment

? New designed optics and data processing enabled to obtain high SN ratio data

Measurement

Mobility calculation

While checking the measurement data, mobility can be easily calculated.

By putting cursor on the inflection point, mobility can be calculated automatically while seeing the logarithmic converted data.

Signal processing

In addition to noise prevention, our unique signal processing enables the system to calculate very small signal data with large noise. The measurement can be applied to the thinner film or high mobility sample, which extends the measurement range.

FET Measurement ( Option )

Adding the optional probe and software to the system is enabled to measure mobility measurement for FET type element.
