Time-resolved Photocurrent Mapping (PCM)

Enabling Innovation in Photosensitive Materials Research

Our PCM mode measures photoelectric response to a time-resolved illumination without interference from unwanted light sources, including the feedback laser. This mode features a laser illumination module and acquisition and analysis software.

time-resolved-photocurrent-mapping-f1-a

A typical photocurrent response to a time-resolved illumination.
The current between the sample and a voltage-biased cantilever is measured before, during, and after the illumination.

time-resolved-photocurrent-mapping-f1-b

Point-by-point mapping of photocurrent spectroscopy.
Photocurrent response in time domain is acquired in each grid point defined on a sample.
