Tumor grade and 1p/19q status are currently the 2 most important factors in therapeutic decision making for patients with these tumors. Histopathology and cMRI studies are still limited(More)
We report a transient absorption study of photocarrier dynamics in transition metal dichalcogenide alloy, Mo 0.5 W 0.5 S 2. Photocarriers were injected by a 400-nm pump pulse and detected by a 660-nm probe pulse. We observed a fast energy relaxation process of about 0.7 ps. The photocarrier lifetime is in the range of 50-100 ps, which weakly depends on the(More)
