Key Features

● All key components utilize original imported equipment, including Nd: YAG laser, preamplifier, photomultiplier tube, energy meter, etc;

● Intuitively reflects the dynamic information such as the separation direction, separation efficiency, and charge lifetime of photogenerated charges;

● An effective means to study the behavior of photogenerated charges on a nanosecond scale, with advantages such as non-contact and non-destructive testing;

● Long-term in-depth collaboration with Professor Dejun Wang from Jilin University, offering technical services including instrument usage, spectrum analysis, and data interpretation.
