Ultrafast Mid-IR Carrier Dynamics in Three-Dimensional Dirac Semimetal Cd3As2

Not Accessible

Your library or personal account may give you access


We investigated ultrafast carrier dynamics in Cd3As2 at 2.6 μm. Single-exponential decay and saturable absorption features are observed. The ultrafast optical nonlinearity suggests that Cd3As2 is useful for mode-locking lasers in the mid-IR range.
