SGA-25

 

CPM Subgap Optical Absorption System

 

Measurement method: Constant Photocurrent Method (CPM )

Monochoromatic light irradiates the sample while in order to keep photo current constant, light intensity is controlled. With the value of irradiation intensity, absorption coefficient can be obtained.

 

 

■ Structure of band gap of semiconductor thin films and various photo conductive materials can be analyzed.


■ The system offers very wider dynamic range of absorption coefficient such as 6 orders of magnitude.

 

■ Real time control of the light intensity generates excellent reproducible data.
