Laser-Transformed C-Zn-Ti as Luminous Photosensor

Laser treated C-Zn-Ti samples are transformed into luminour IR photosensors as a result of rapid annealing and cooling of the selective sites, leaving the system in a state of disorder. It is hypothesized that the disordered system introduced mid-gap states into the intrinsic wide bandgap material, which in turn contributed to the observed phenomenon.

This was the initiation to our research journey, we are forever indebted to our professors that guided us every step along the way.
