Carrier Dynamics

- MoS2 is a typical material of transiton metal dichalcogenide family,  which exhibits unique properties when thickness reduces to monolayer.
- Strong photoluminescence and high carrier mobility makes it a promising candidate for furture photonic and FET applications.
- Our ultrafast measurement utilizes optical 400nm-pump 800nm-probe spectroscopy to reveal the relaxation dynamics of photo-excited carriers in both bulk and monolayer MoS2.
- Measurement is carried out at ambient pressure for different pump fluences.
