双束光电流法(DBM)系统PTS-3-DBM
名称： 双束光电流法(DBM)系统PTS-3-DBM
型号： PTS-3-DBM
品牌： Sciencetech
PTS-3-DBPM具有与PTS-1和PTS-2系统相同的测量IV，光谱响应和量子效率的能力，但是增加了双光束光电导方法的强大技术。DBPM系统基于在光子能量范围内保持恒定的光电流以获得恒定的准费米能级。此外，DBPM系统具有改变偏置光源强度的附加功能。这会改变电子空穴和准费米能级，以产生有关缺陷状态的其他信息。请与科学技术**联系以获取更多信息。
PTS-3-DBPM包括：
?IV测试
?光谱响应
?量子效率/ IPCE
?双束光电流法(DBM)
(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
