Terahertz Emission and Ultrafast Carrier Dynamics of Ar-Ion Implanted Cu(In,Ga)Se<sub>2</sub> Thin Films
We investigated THz emission from Ar-ion-implanted Cu(In,Ga)Se<sub>2</sub> (CIGS) films. THz radiation from the CIGS films increases as the density of implanted Ar ions increases. This is because Ar ions contribute to an increase in the surface surge current density. The effect of Ar-ion...
