(PTS-3-DBM) Dual Beam Photocurrent Method

The PTS-3-DBPM has the same ability to measure IV, Spectral Response, and Quantum Efficiency as the PTS-1 and PTS-2 systems, but adds the powerful technique of the Dual Beam Photoconductivity Method. The DBPM system is based on maintaining constant photocurrent over the range of photon energy to get constant quasi-Fermi levels. Furthermore, the DBPM system has the additional capability to vary the bias light source intensity. This changes the electron-hole and quasi-Fermi levels to yield additional information about defect states. Please speak to a Sciencetech Technical Specialist for further information.

 

PTS-3-DBPM Includes:

-IV Testing

-Spectral Response

-Quantum Efficiency/IPCE

-DBPM Measurements
